... polymerization, and the hydrolysis products distribution of PSF was calculated from the pH changes during the hydrolysis process of PSF. The characterization of PSF and total phosphorus (TP) removal by PSF were studied in comparison with that of polyferric aluminum (PFA). The results revealed tha ...
