Abstract
Copper adsorption by Rhizopus arrhizus, Cladosporium resinae and Penicillium italicum was studied using a copper-selective electrode. Copper adsorption by C. resinae and P. italicum obeyed the Freundlich and Langmuir isotherms for single-layer adsorption whereas R. arrhizus followed the BET isotherm for multi-layer adsorption. Temperature had little effect on adsorption over the range 4–25°C. Mineral acids were effective for desorption of copper from preloaded biomass, the efficiency of desorption increasing with decreasing pH. Other cations were also capable of copper desorption with zinc showing the greatest efficiency and sodium the lowest.
