The Preparation and Characterization of a New High Polymeric Flocculant-Polymeric Aluminum Ferric Sulfate Chloride

摘要

With AlCl_3 and FeSO_4 as the major raw material, the preparation process of a new high polymer flocculant-polymeric aluminum ferric sulfate chloride(PAFSC) was researched, to offset the polymeric aluminum and the polymerization iron flocculants' lacks, and draw their strong points. The product was characterized by Al-Fe-Ferron timed complex colorimetric, IR and XRD methods, to study the flocculant's morphological characteristics. The results show that The PFASC, with better coagulating property than the market PAC, has higher contents of Alb and Al-OH-Fe bond, and the introduction of iron restrains the forming of Al-OH-Al.
