Study on Preparation of Poly Aluminum-ferric Silicate Flocculants and its Performance
摘要
Abstract
Poly aluminum ferric silicate was prepared from high - alumina - bearing fly ash, sulfu-ric acid cinder and industrial waste acid. Based on the chemical and physical property of the high - alumina fly ash, the extraction process of silica, aluminium and ferrum of " solid - phase pyroly-sis and acid leaching" was established by taking trona as cosolvent. The best synthesis conditions of poly aluminum - ferric silicates was reached when molar ratio of silicate and alumina is 1 : 0.7, molar ratio of silicate and alumina is 1 : 0.5, pH value is 2, polymerization temperature is 60?. Finally, the product was characterized using XRD, IR and SEM. The result shows that the poly a-luminum ferric silicate from this fabrication process was of good polymerization and big polymer size. Compared with the traditional flocculants, this new product has better flocculation performance.关键词
