This study was conducted to Determine the Concentrations of Some Heavy metals in water samples obtained from Gwaigwaye, Maska and Zobe Dams in Dry and wet Seasons. The Dams provides water for Drinking, Fishing, Farming and other Agricultural Activities to the Neighbouring Communities. In this study water samples collected from Gwaigwaye, Maska and Zobe Dams in Dry and wet Seasons were Analyzed for Some Heavy metals namely, Cadmium, Cobalt, Copper, Nickel, lead and zinc. After Samples Digestion, microwave plasma atomic emission spectroscopy(MPAES) was used for the Determination of the Metal concentrations and their Levels were compared with permissible limits set by local and international standard regulatory Authorities. From the result of the Analysis, the Concentrations of the Heavy metals in Dry season in mg/L ranged as follows. 0.00±0.00 to 0.03±0.00 mg/L for Cd, 0.02±0.00 to 0.084±0.002 mg/L for Co, 0.057±0.003to 0.186±0.003 mg/L for Cu, 0.03±0.00 to 0.19±0.005 mg/L for Ni, 0.00±0.00 to 0.01±0.00 mg/L for Pb and 0.06±0.02-0.193±0.003 mg/L for Zinc. Similarly, the Concentrations of metals in wet season in(mg/L) ranged as follows, 0.00±0.00 to 0.027±0.002 for Cd, 0.02±0.002 to 0.071±0.002 for Co, 0.051±0.003 to 0.103±0.014 for Cu, 0.029±0.003 to 0.12±0.013 for Ni, 0.00±0.00 to 0.00±0.00 for pb and 0.057±0.002 to 0.160±0.003 for Zinc. The Concentrations level of Cd, Co and Ni in water samples from Maska, Gwaigwaye and Zobe Dams in dry season were above the permissible set by WHO/SON. However, Cu, Pb and Zn were within the permissible limit of WHO and SON in all the Dams in dry and wet seasons. The Result of Statistical Analysis indicated no Significant Difference between the Metals in all the Dams in both Dry and Wet seasons as p values were greater than 0.05( p >0.05).","PeriodicalId":13723,"journal":{"name":"International Journal of Advanced Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141678385","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 study delves into the intricate process of producing and enhancing zeolite material derived from economically viable sugarcane bagasse by employing hydrothermal treatment. It meticulously explores four pivotal process variables: particle size (90-200 µm), reagent (0.5 M NaOH+1.5 M NaCl) ratio (0.5-1), contact time (40-72 hr), and temperature (70-100oC), by utilizing 24 full factorial design to optimize synthesis conditions. The investigation carefully delineates the nuanced impacts of these variables on the resulting zeolite porosity. After 16 experimental runs, the study identified the optimal synthesis conditions as follows: a particle size of 90 µm, a reagent ratio of 1, a contact time of 72 hr, and a temperature of 100oC. The fit statistics that signified the adequacy and significance of the developed model are R² = 0.9965, Adjusted R² = 0.9827, Predicted R² = 0.9018; Adeq Precision = 26.6195; Std. Dev. = 1.69 and C.V = 2.72%. Furthermore, the synthesized zeolite exhibited potentially a heightened adsorption capability due to its amplified porosity. This opens up promising avenues for wastewater treatment, offering effective solutions to a myriad of environmental concerns. This approach not only addresses the pressing issue of waste management but also underscores the potential of transforming waste into valuable resources for sustainable development.\u0000 ","PeriodicalId":13723,"journal":{"name":"International Journal of Advanced Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140236349","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}

In the past, spices used to be worth their weight in gold, and cloves were no exception. Today, cloves remain a popular spice that gives many dishes subtly sweet warmth. A drop of clove oil is 400 times more powerful as an anti-oxidant than wolf berries or blueberries. Cloves contain a lot of manganese, a mineral that helps your body manage the enzymes that help repair your bones and make hormones. Manganese can also act as an antioxidant that protects your body from harmful free radicals (unstable atoms that cause cell damage). Cloves are a fragrant, dense spice that can be added to both savory dishes (such as curries) and sweet desserts (such as pumpkin pie). They're full of powerful nutrients that help protect your cells from damage. Some natural compounds in cloves interfere with medicines or cause side effects that can be life-threatening. So, it's safest to only cook or bake with cloves and enjoy this spice's health benefits that way. Clove is utilized in cosmetics, medicine, gastronomy, and agriculture due to its abundance of bioactive components such as gallic acid, flavonoids, eugenol acetate, and eugenol. Clove essential oil has been revealed to have antibacterial, antinociceptive, antibacterial activities, antifungal, and anticancerous qualities. Anti-inflammatory chemicals, including eugenol and flavonoids, are found in clove that help decrease inflammation and alleviate pain. The anti-inflammatory and analgesic qualities of clove oil have made it a popular natural cure for toothaches and gum discomfort. Due to its therapeutic potential, it has been used as a bioactive ingredient in coating fresh fruits and vegetables. This research article outlines the potential food processing applications of clove essential oil. The chemical structures of components, bioactive properties, and medicinal potential of clove essential oil, including phytochemical importance in food, have also been thoroughly addressed.\u0000 ","PeriodicalId":13723,"journal":{"name":"International Journal of Advanced Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140261376","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}
