摘要：
In this study, the possible synergistic retention effects of the colloidal magnesium aluminum hydroxide with cationic polyacrylamide or anionic/cationic polyacrylamide complexes were investigated. The results showed that the colloidal magnesium aluminum hydroxide significantly improves the retention efficiency of cationic polyacrylamide (CPAM), which is either pre-added or post-added, at relatively low addition levels. It also shows good synergistic retention effect with the complexes of anionic polyacrylamide (APAM) and CPAM at high mass ratio.
