In this research, the adsorption of Zinc and Cobalt using non-living cells of Phanerochaet crysosperium PTCC 5270 has been investigated. For the determination of optimum condition, the effects of pH, biomass concentration, contact time, and temperature evaluated. Our results showed that maximum adsorption of Zn and Co was at pH= 7 and pH=4 respectively. Also, the optimum time for biosorption obtained about 120 min and 90 min for Zinc and Cobalt respectively. Based on the results of this study, it was found that the best temperature for removal of zinc and cobalt metals is 35 ° C. Finally, the maximum biosorption was observed for both metals at a concentration of 5 g / l of non-living fungus. Finally, at the optimum point, the maximum biosorption for zinc and Cobalt were measured about 15.46 mg/g and 14.32 mg/g respectively. According to the results obtained from this research, it can be said that non-living Phanerochaet crysosperium PTCC5270 is a suitable and inexpensive biosorption for removing heavy metals such as Zinc and Cobalt from aqueous solution and can be used in industries as a biological method.
