Abstract

Biosorption of heavy metals can be an effective process for the treatment of industrial wastewater that contains heavy metals. In this paper, the interference effects of co-ions on the biosorption of Cu2+ by using a biosorbent derived from the biomass of marine alga Durvillaea potatorum were investigated. The adsorption capacity of biosorbent for Cu2+ from aqueous solutions containing co-ions of light metal ions (K+, Na+, Ca+, and Mg2+), other heavy metal ions (Ag+, Mn2+, Co2+, Ni2+, Zn2+, Fe3+, Cd2+, and Pb2+), and anionic ligands (EDTA, CO32-, SO42-, and PO43-) were obtained. The results showed that Cu2+ uptake is significantly affected by other heavy metals and EDTA in solution (1.5-100% suppression) but not significantly affected by light metal ions and other anionic ligands studied.
