The physico-chemical properties of the produced water were determined and the activated carbon was characterized in terms of pH and surface characteristics. The effects of adsorption process variables on the adsorption capacity of the activated carbon were evaluated and optimized using response surface methodology. The adsorption process variables considered and their range of values are adsorbent dosage of 2.0 to 5.0 g, contact time of 30 to 60 mins and temperature of 35 to 60℃. The physico-chemical properties of the produced water before treatment revealed that the produced water was contaminated with high concentration of hydrocarbons and other contaminants. Elemental composition showed that the activated carbon contained predominantly CaO (52.61%) and P2O5 (43.05%). The BET surface area, pore volume and pore size of the activated carbon were found to be 321.79 m2.g-1, 0.1624 cm3.g-1 and 2.10 nm respectively which indicate activated carbon has a mesoporous structure. The maximum amount of total hydrocarbon content adsorbed was found to be 607.27 mg.g-1 which was achieved using activated carbon dosage of 2.00 g, contact time of 40.56 mins at a temperature of 35℃. The high and close R-squared values of the experimental and predicted values of the total hydrocarbon content indicate reasonable agreement and hence showed the effectiveness of response surface methodology in modeling the removal of total hydrocarbon content in produced water. The high amount of total hydrocarbon content adsorbed showed that activated cow bone carbon is effective and efficient as a low cost adsorbent alternative for the degradation of hydrocarbon in waste water streams.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"08 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86389027","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 evaluated the effect of AML against experimental MSG-induced cardiac oxidative stress. Thus, rats orally and for 14 consecutive days received MSG (8000 mg/Kg/day). Cardiac oxidative stress bio-indicators: malondialdehyde, MDA, nitric oxide, NOX, glutathione peroxidase, GPX, superoxide dismutase, SOD, catalase, CAT, albumin, ALB, total protein, TP, magnesium, Mg, and zinc, Zn were determined. MSG significantly (p < 0.05) increased MDA and Zn but decreased others without altering NOX content compared to control rats in consistency with induction of cardiac oxidative stress in the rats. AML dose-dependently mitigated these MSG-induced oxidative effects. Thus, AML can protect against MSG-induced cardiac oxidative stress in the rats.

Fuel cell generally applies the principle of electrochemistry in which chemical energy is converted directly into electrical energy. Amongst the league of fuel cells, the proton exchange membrane fuel cell is the most promising. However, the central component of PEMFC is the ionic polymer membrane that must be rendered conductive. This study showed that the measure of sulphonation is pivotal in achieving conductivity of the polymer for fuel cell application. The study revealed that for an optimum conductivity to be achieved, optimum degree of sulphonation (DS) is needed. The recognized factors that affect the optimum degree of sulphonation were the type of sulphonating agent (as chlorosulponic acid achieved 39.04% and 50.21% differential increment over both sulphuric acid and fuming sulphuric acid, respectively), sulphur content (while the lowest Sc of 1.76% achieved 9.13% DS, the highest Sc achieved 20.04% DS), optimum acid concentration (as DS of 20.04 % was achieved with 1.6 mmol/g as against 2.0 mmol/g of 16.76 %), nature of the polymer base material (as more –SO3H groups attached to aliphatic polymers than aromatic), optimum time and stirring speed, optimum temperature, and optimum weight of the base polymer. The study was able to unravel that the degree of sulphonation can be determined via elemental sulphur analysis either by analytical or titrimetric method. The study also showed that the degree of sulphonation can be predicted correctly using a predictive model.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75455412","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 adsorbents were characterized using Energy-dispersive X–Ray Fluorescence (EDXRF) and Scanning Electron Microscopy (SEM). The adsorption parameters were determined based on optimal conditions of adsorbent dosage (0.90 g), initial adsorbate concentration (10.00 mg/L), pH (7.00), contact time of 60.00 mins (AACCHCC) and 80 mins (control) and at 300 rpm. Optimum percentage adsorptions of 98.29, 88.71, 99.47 and 60.30% respectively were obtained when the control was used as adsorbent and 99.99, 99.93, 99.80 and 86.15% respectively for the AACCHCC. EDXRF showed that AACCHCC was richer in K, Ca, and Ce than the control while SEM showed wider dispersed polycrystallites. Langmuir and Freundlich isotherms used to describe the equilibrium data showed better fits for Langmuir (a monolayer homogenous model) while the kinetic studies fitted the pseudo-second order kinetic better. The study has shown that AACCHCC is a more effective adsorbent with a shorter uptake time of 60 mins than the control.","PeriodicalId":15357,"journal":{"name":"Journal Of Chemical Society Of Nigeria","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84542188","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}
