摘要 采用自制载钛壳聚糖(TCTS)与聚硅酸铁(PSF)制备出一系列不同n(Fe)/n(Ti)的复合絮凝剂载钛壳聚糖复合聚硅酸铁(TCTS-PSF),分析了复合前后样品的结构与处理聚丙烯酰胺(PAM)废水的性能,并考察了n(Fe)/n(Ti)对产品结构及性能的影响。结果表明,复合后的样品中PSF与TCTS之间存在配位作用与氢键作用,并发生空间网状交联,形成疏松的簇状无定型聚合物。复合后的样品性能优良,当n(Fe)/n(Ti)=0.75、絮凝剂投加量为0.2 mL/L时,对100 mg/L的PAM废水的去除率达97%。

Abstract: A series of composite flocculants-chitosan-coated titanium (TCTS) compositing polysilicate ferric (PSF) with different n(Fe)/n(Ti) are prepared from self-made TCTS and PSF.The structures of flocculants samples before and after compositing are analyzed,and their performances in treating with polyacrylamide (PAM) wastewater are evaluated as well.The effect of n(Fe)/n(Ti) on the structure and the performance of the TCTS-PSF is studied.It is found in the composited samples that the coordination and hydrogen bond exists between TCTS and PSF,and a loose cluster amorphous polymer is formed by space network crosslinking.The composited sample has excellent flocculation performance.The removal rate of PAM can reach 97% when n(Fe)/n(Ti)=0.75,flocculant dosage is 0.2 mL·L-1 and the PAM concentration is 100 mg·L-1.
