The preparation of activated carbon from agroforestry waste for wastewater treatment

The scope of this study was to produce activated carbon from local agroforestry wastes (marula fruit stones, jackalberry seeds, eembe seeds, efukwa shells and eembu seeds) and assess the efficiency of the produced carbons in removing dyes and metal ions from wastewater. Preparation of activated carbons from efukwa shells, marula fruit stones, jackalberry seeds, eembe seeds and eembu seeds are described in this study....

Photolysis of 4-oxazoline-2-one derivative in diverse solvent environments

The photolysis of 4,5-diphenyl-3-(4-methylphenyl)-4-oxazolin-2-one in benzene or cyclohexane in the presence of singlet oxygen using UV light affords benzil, N-4-methylphenyl benzamide and N,N-dibenzoyl-4-methyl aniline. When the same reaction is carried out in protic solvents, the formation of benzil, N-4-methylphenyl benzamide, N,N-dibenzoyl-4-methyl aniline  and benzoic acid  is observed. The...
