Biosorption is fast becoming an attractive method for heavy metal contaminated wastewater treatment. This paper investigates the uptake capacity and removal of lead (II) by Pleurotus ostreatus biomass under the influence of biomass concentration, initial pH of heavy metal containing solution, contact time and initial Pb(II) concentration as to ascertain the(More)
The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach of using the half-saturation concentration of biosorbent to rapidly determine the uptake, kinetics and mechanism of biosorption was employed together with cost per unit uptake analysis to(More)
Arsenic (As) analysis of 150 boreholes in the south-eastern part of Ghana (Accra, Eastern and Volta regions) revealed low to medium concentrations in the range of 2-39 μg l-1, with only 2% of boreholes tested having arsenic concentration exceeding 10 μg l-1 of the WHO (2004) maximum permissible level of arsenic in drinking water. The measurements were(More)
This paper addresses how the current changes in climate and economic landscape affect the focus of engineers and scientists in managing the abundant but finite water resources. The important concept of sustainability where the delicate balance between human needs and protection of the environment is further stressed in light of emerging advanced(More)
