Abstract :In this study, the simultaneous adsorption process of Crinsert ignore into journalissuearticles values(VI);, Feinsert ignore into journalissuearticles values(III); by R. arrhizus and C. vulgaris and Cuinsert ignore into journalissuearticles values(II); in pairs of metal mixtures were investigated and compared to single component systems. The capabilities of the fungal and the algal biomass to bind two metals simultaneously in solution are shown as a function of pH, metal combinations and levels of metal concentration. The effects of the co-presence of Crinsert ignore into journalissuearticles values(VI);-Feinsert ignore into journalissuearticles values(III); and Crinsert ignore into journalissuearticles values(VI);-Cuinsert ignore into journalissuearticles values(II); ions together in aquatic solutions on the biosorption of Crinsert ignore into journalissuearticles values(VI);, Fe insert ignore into journalissuearticles values(III); and Cuinsert ignore into journalissuearticles values(II); ions were investigated in terms of initial rates of biosorption and equilibrium metal removal. Optimum pH for the biosorption of Crinsert ignore into journalissuearticles values(VI); and Feinsert ignore into journalissuearticles values(III); was determined as 2.0 whereas higher biosorptive uptake of Cuinsert ignore into journalissuearticles values(II); was obtained at pH 4.0 Since the initial biosorption rates and equilibrium metal removal decreased with increasing concentration of the accompanying metal ion, the interactive effects of Crinsert ignore into journalissuearticles values(VI);-Feinsert ignore into journalissuearticles values(III); and Crinsert ignore into journalissuearticles values(VI);-Cuinsert ignore into journalissuearticles values(II); on both microorganisms were found to be antagonistic.
