Synthesis and Characterization of PSAF@Starch Inorganic-Organic Hybrid Flocculant
摘要
Abstract
Fly ash mixed with solid sodium hydroxide were roasted in order to be activated,and after the methods of acid leaching and stewing, the starch and initiator K 2S2O8were added.The PSAF@starch hybrid flocculant was prepared by one step method of hydrolysis and polycondensation.The following factors such as starch content and initiator dosage were considered on the flocculation performance.The study found that when starch content was 40%, the initiator dosage was 1%, the turbidity removal efficiency of low turbidity analog water can reach to 76.3%.The conductivity of flocculant showed good linear relationship with concentration, and the product reserved more obvious starch glucose C-O-C stretching vibration absorption peak at 1086 cm-1, higher half-life temperature than mixture of PSAF-starch,better thermal stability.It showed that the hybrid product was combined by covalent bond.关键词
