Abstract—Polymer Si-Fe (PSF) coagulant was prepared by co- high as expected. On the other hand, the mechanism of
polymerization. The oxidization of PSF was investigated by using removing DOMs by coagulation process is still the
jar test for humic acid (HA) solution sample and measuring cooperation of adsorption/charge-neutralization, bridging and
