Abstract

We found that a new heavy metal precipitant, disodium N,N-bis-(dithiocarboxy)piperazine, both precipitates Cu2+ ions removes the dye from wastewater. The precipitation was based on a coordination polymerization reaction while the removal of the dye could be mainly attributed to an hydrophobic adsorption at pH 7.
