Several cannabinoids have been isolated from the leaves and flowers of Cannabis sativa, with some formulated into drugs for the treatment of certain ailments. In this study, the isolation and characterization, using chromatographic and NMR techniques, of cannabinoids from the stems of Cannabis sativa was carried out. Cannabis stems were collected from the Department of Biology, Nasarawa State College of Education, Akwanga. Fractionation and purification of the extracts were carried out using silica gel column chromatography. A high performance liquid chromatography equipped with an electrostatic light scattering detector, ultraviolet detector (UV) and mass spectrometry (MS) was used to determine the mass of isolated cannabinoids. Two cannabinoids, cannabinol and cannabinol methyl ether were isolated from fractions of the hexane, ethyl acetate and methanol extracts, and were characterized using a JEOL Delta GX 400 MHz FT nuclear magnetic resonance spectrophotometer. The isolation of these cannabinoids in sample analysed confirms that Nigeria cannabis contained cannabinoids, and this also shown that the stems of cannabis can be used as stimulants to reduce the effects and symptoms of glaucoma and treat cases related to epidermolysis bullosa because of the isolation of cannabinol.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140681448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water samples were collected from North Bank, High-Level, Tse-Poor and Kanshio areas of Makurdi metropolis over a period of two weeks and analysed for physicochemical parameters using instrumental methods. The results revealed that most of the parameters were within the limits of Nigerian Standard for Drinking Water Quality (NSDWQ) and the World Health Organization (WHO). Parameters that were within the permissible limits in all the samples (100 %) were electrical conductivity, total dissolved solid, chloride, fluoride and temperature. Their mean values were 262.91±148.33 µS/cm, 133.13±72.86 mg/L, 93.08±48.30 mg/L, 0.44±0.23 mg/L and 28.46±1.27 oC respectively. The compliance of other parameters such as dissolved oxygen, turbidity, total hardness, nitrate and pH with NSDWQ and WHO standards ranged from 50 – 91.67 % of the samples. Meanwhile the reference value for the level of total suspended solids in drinking could not be obtained from the available literature. It was concluded that the well water in Makurdi contains some properties at variance with set standards and should be treated before consumption. There is also a need for periodic assessment of the well water quality to guide against the consumption of water with deteriorated quality.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"1 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140681122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of solution pH, and contact time on the adsorbent for the removal of Pb(II) and Ni(II) ions were evaluated. To study the adsorption kinetics of Pb(II) and Ni(II) ions onto Curcuma longa Rhizome, pseudo-first-order, pseudo-second-order as well as three diffusion models: intraparticle diffusion model (Weber and Morris model), film diffusion model (McKay model) and liquid film Models were used. The sorption kinetics can be described well by the pseudo-second-order model due to the closeness between the qexp ( 49.26 mg/g) and qcal (52.63 mg/g) for Pb(II) and qexp (57.60) and qcal (55.56 mg/g) for Ni(II) ions. Moreover, the rate limiting step are liquid film and intraparticle diffusion controlled. In addition, the results suggest that Curcuma longa Rhizomes are very effective adsorbent for the removal of Pb(II) and Ni(II) ions from aqueous medium. This will serve as an indicator to consider in the design for waste water treatment plant for heavy metal detoxification using Curcuma longa Rhizome.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"18 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140226100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals found in solid wastes may likely be released into the environment via flood runoff. To assess whether the contaminants can affect the groundwater, soil samples were collected for analysis in two seasons – dry and wet seasons. To determine level of the metals in the soil matrix, the samples were subjected to acid digestion followed by atomic absorption spectroscopy analysis. The different solid-phases associated with heavy metals were evaluated from the soil samples by using sequential extraction method. The geo-accumulation index and mobility factor were considered to assess the level of contamination and migration of the metals present in the soil. The soil metal contents strongly correlated with the soil pH and organic matter. The exchangeable fraction has Cr > Pb > Co in the order of its mobility in the soil, whilst in the residual fraction suggesting the most immobile species with Pb > Co > Cr > Ni present in the soil. The geo-accumulation index showed that the degree of pollution of the dumpsite during the dry and wet seasons was mostly unpolluted. The study indicates that the metals of interest may not likely pose environmental risk due to their relatively low concentrations and the chemical species in which they exist in soil.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140263104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This present study was aimed at analyzing the impact of various roofing materials, galvanized iron tank and industrial activity on rainwater quality by determining the physicochemical characteristics, bacteriological properties and the metal composition of the roof types and storage medium. Rainwater was harvested from Cameroun zinc, stone-coated tiles, asbestos, corrugated iron roofs run-offs, and stored rainwater in galvanized iron tank and directly from the sky (control) in the urban and rural areas of Rivers State between the months of April-July, 2018. The results will be compared with the standards (NAFDAC, USEPA, WHO and NSDWQ) for drinking water quality and Water Quality Index (WQI) ratings since there is no standard for rainwater quality. Roofs ages from <5, 5-10, 15-20, and >25 years in service conditions and stored rainwater in storage vessels for the duration of one year and above were considered. Heavy metals were analyzed using Flame-AAS; other parameters were analyzed using standard methods. The WQI ratings were calculated using the weighted arithmetic method. Results obtained in both areas gave mean values ranging from 6.10-6.90 for pH, Temp., (20.00-28.00 oC), EC (17.00-132.00 µ?/cm), E. coli (no detection). Other results (mg/L) were; TDS (15.50-71.67), TSS (19.00- 84.67), Pb (0.00-0.23), Cr (0.00-0.12), Zn (0.01-0.03), Fe (0.01-0.22) and Al (0.00-1.61).The WQI ratings gave excellent water to unfit for drinking water quality in both areas. Generally, harvested rainwater is not free of contaminations because of its catchment/storage systems due to atmospheric pollution and leaching of the roofing material; hence, it should be treated before being used for domestic and potable usages.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"27 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140263812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
