Sorption of lead (ii) ions by granular activated carbon from animal horns: A comparative study
The physico-chemical properties of wastewater effluent from the plants of a brewering industry in Nigeria have been analyzed. The lead ions removal capacity of Granular activated carbon from animal horns and its comparison with commercial granulated activated carbon (GAC) was studied. Batch kinetics and isotherm studies were carried out for the adsorption of Pb2+. The equilibrium...

Effect of varying concentration of sodium nitrate on biological oxidation of petroleum hydrocarbon polluted water
The bioremediation of petroleum hydrocarbon polluted water using Aspergillus niger and varying concentrations of sodium nitrate was investigated in this study. Five samples of petroleum hydrocarbon polluted water innoculated with A. nigercontaining 0.05, 0.1, 0.2, 0.3 and 0.4 M NaNO3(aq) and the control was monitored for parameters such as Total Hydrocarbon Content (THC), Biological Oxygen...
