Heavy Metal Removal by the Waste Biomass of Penicillium chrysogenum

摘要

Metal sorption capacity of the granulated biosorbent derive from the waste biomass of Penicilliumchrysogenum was examined. The potential metal sorp- tion abilities of the biosornbent were estimated as the ion-exchange capacity, using a potentiometric titration. The total binding capacity, calculated for the pH range 3 to 8 was about 511 μeq/g dry weight. The granular biosorbent was capable of Cd, Zn, Cu and Pb binding.
