An inorganic polymer, liquid poly-silicic–ferric (PSF) coagulant, with different Si/Fe molar ratios was prepared using water glass, FeSO 4 ·7H 2 O and NaClO 3 by co-polymerization. The solid PSF made from liquid PSF by two different solidification approaches was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. A comparison of coagulation...
