Dendrimer-OH / titania composites used as metal chelates.

Dendrimer-OH / titania composites can be used as metal chelates to treat wastewater with metal ions, especially for industrial plating wastewater treatment. Optimum pH value of electroplating wastewater that contain various metal ions was different, Cu2 + and Cr3 + optimum treatment pH value was 7, the metal ion removal rates was 96.6%, 99.9%, and optimum treatment pH value of Ni2+ was 9, removal rate was 99.8%.
