[Performance of Novel Macromolecule Flocculant in the Treatment of Wastewater Containing Cr (VI) Ions].

A novel macromolecule flocculant, polyethyleneimine-sodium xanthogenate (PEX), was applied in the treatment of wastewater containing Cr(VI) ions. The trapping performance of PEX for Cr(VI) ions was studied, and effects of selective important factors, such as initial Cr(VI) concentration, pH value, coexisting inorganic substance and turbidity etc., on the removal of chromium by PEX were investigated.
