  • Kinetics of Acidic Mn(VII) Oxidation of Acetaldehyde in Aqueous and 5% Ethanol-Water Solvents

    Kinetics of Acidic Mn(VII) Oxidation of Acetaldehyde in Aqueous and 5% Ethanol-Water Solvents 1*Latona Dayo Felix, 2Adejoro Ajibade 1*Department of Chemical Sciences, Osun State University, PMB 4494 Osogbo, Nigeria. 2Department of Chemistry, University of Ibadan, Nigeria. Kinetics of acidic Mn(VII) oxidation of acetaldehyde in aqueous and 5% ethanol-water solvents were studied via pseudo-first order condition at λmax 525nm. The reaction showed a first order dependence with respect to acetaldehyde concentration, [Mn(VII)], fractional order to [H+] and independent on the ionic…

  • Evaluation of cassava (Manihot Esculentum) seed waste Activated carbon for kinetic study on methylene blue dye adsorption from aqueous solution

    Evaluation of cassava (Manihot Esculentum) seed waste Activated carbon for kinetic study on methylene blue dye adsorption from aqueous solution Gumus R.H. Department of Chemical and Petroleum Engineering, Niger Delta University P.M.B 071 Wilberforce Island. Bayelsa State. Nigeria The effect of activation temperature on activated carbon was studied at 400o C, 500oC and 600oC respectively. The characterization properties showed that increased in temperature reduces yield, moisture content, ash content and volatile content but increased fixed carbon, pore volume and porosity….

Soyelu* Department of Crop Production and Protection, Obafemi Awolowo University, Ile-Ife 220005, Osun State, Nigeria Fine powders of orange peel (Citrus sinensis), scent leaf (Ocimum gratissimum), morinda leaf (Morinda lucida) and lemongrass (Cymbopogon citratus) were applied against 2-day-old maize weevils, Sitophilus zeamais with a view to identifying non-chemical control agent(s) of the weevils. Growth rate, antioviposition effect, repelling efficacy and mortality due…

  • Synthesis of graphene oxide using tea-waste biochar and its application

    Synthesis of graphene oxide using tea-waste biochar as green substitute of graphite and its application in de-fluoridation of contaminated water Swapnila Roy Department of Chemical Engineering, Jadavpur University, 188, Raja S.C. Mullick Road, Kolkata – 700 032, India   In the present study, pyrolysis of domestic tea waste was carried out to yield bio-char. The biochar obtained was further used as a substitute for graphite in synthesis of graphene oxide (GO) in the conventional process. GO obtained was further applied…
