It is observed that Cu2þ uptake is significantly decreased in the presence of HPO2 4 and SO2
4.The observed effect is less significant for Fe3þ and Cr3þ in the presence of SO2 4 and HPO2 4 respectively.This could possibly be due to the metal–anion complex formation and the nature and charges of the complex species present.Blank solutions show precipitation in the case of Fe3þ/HPO2 4 solution, leading in complete removal of Fe3þ from solutions.Precipitation along with ion exchange is resulting in higher removal of Fe3þ from the solution than ion exchange or precipitation alone.Finally, anion co-removal is significant, reaching 80% for HPO2 4 ions.
