Synthesis and characterization of composite flocculant PAFS-CPAM by response surface methodology
摘要
Abstract
The composite flocculant was prepared by polymerizing CPAM (a cationic flocculant P: acrylamide-methacryloxyethyltrimethyl ammonium chloride-acryloxyethyltrimethyl ammonium chloride) and PFAS (polymeric aluminum ferric sulfate). The morphological distribution of Fe and Al was studied by using Ferron analysis,and the morphology of the copolymer was observed using scan electron microscopy. The Box-Behnken mathematical relational model between CODCr removal rate and affecting factors was established,and the technique composing PAFS-CPAM was optimized. The optimum synthesis conditions were: react temperature 61℃,react time 74 min,and Fe/CPAM mass ratio 28,respectively. At these optimized conditions and using 50 mg o L-1 PAFS-CPAM flocculant prepared,CODCr removal and turbidity removal rates were 80. 86% and 97. 50%,respectively.关键词
