Pb2+ biosorption

Environmental contamination by toxic heavy metals is causing a serious problem worldwide. The objective of the study was the utilization of eco-friendly and low-cost effective biomass of actinomycetes in the removal the toxic heavy metals (Cu2+, Pb2+, and Cd2+) from wastewater. Out of sixty-six isolates of actinomycetes were isolated from different drains in Egypt, eleven isolates removed studied heavy metals (Cu2+, Pb2+, and Cd2+) singly above 70% were selected to remove metals from ternary mixtures. The biosorption by dead biomass for all isolates was higher than that by living biomass.

The effect of pretreatment on the Pb2+ biosorption capacity of fungal biomasses, Aspergillus versicolor, Metarrhizium anisopliae var. anisopliae, and Penicillium verrucosum, was investigated. For this purpose, the biomasses were subjected to physical treatments such as heat and autoclaving, and chemical treatments such as sodium hydroxide, formaldehyde, gluteraldehyde, acetic acid, hydrogen peroxide, commercial laundry detergent, orthophosphoric acid and dimethyl sulfoxide.
