An assessment of toxic metal biosorption by activated sludge from the treatment of coal-gasification effluent of a petrochemical plant

A standardized EDTA treatment was used to chelate sludge-bound metal-ions from activated sludge from the coal-gasification effluent of a petrochemical plant. The sludge was then equilibrated with solutions increasing to 100 mg l −1 Ni 2+, Cu 2+, Fe 2+, Zn 2+ and Cr 3+ individually and in combination...
