The adsorption effect of three mushroom powder on Cu2+ of low concentration

摘要

Biosorption of heavy metal ions is one of the focuses of current research. In this paper, the powder of Agrocybe aegerita, Hericium erinaceus, Pleurotus ostreatus were chosen as biosorbent to study their effect on the adsorption of Cu2+. The results showed that the sequence of adsorption capacity is Agrocybe aegerita > Pleurotus ostreatus > Hericium erinaceus. The adsorption is also affected by the initial concentration of Cu2+, adsorption time and concentration of mushroom powder itself.
