采用[Al+Fe]-Ferron逐时络合比色法研究了典型聚磷氯化铝铁溶液的形态转化,结果表明,聚磷氯化铝铁的形态转化主要由P(/Al+Fe)、OH(/Al+Fe)和nAl/nFe等因素决定,聚磷氯化铝铁的形态转化特征是优势形态之间的转变。通过对模拟悬浊水样的絮凝实验,对其除浊性能进行了考察,通过测定zeta电位对其水解物的电动特性进行了研究,结果表明,聚磷氯化铝铁水解聚合产物的电动特性与P(/Al+Fe)、OH(/Al+Fe)和nAl/nFe的变化密切相关,聚磷氯化铝铁是通过电中和、吸附架桥和沉淀网捕作用起混凝作用的,三种作用的综合能力越强,其混凝效果就越好。
The morphological transformation of typical polyphosphates was investigated by [Al + Fe] -Ferron colorimetry. The results showed that the morphological transformation of polyphosphates was mainly composed of P (/ Al + Fe) , OH (/ Al + Fe) and nAl / nFe and other factors, the morphological transformation of polyphosphates is the transition between the dominant morphologies. Through the flocculation experiments on simulated suspended water samples, the turbidity removal performance was investigated. The zeta potential was used to study the electrokinetic properties of hydrolyzate. The results showed that the electrodynamic properties of hydrolyzed poly It is closely related to the change of P (Al + Fe), OH (Al + Fe) and nAl / nFe. Poly aluminum phosphorus ferrochloride is coagulated by electric neutralization, adsorption bridging and sedimentation , The more comprehensive the three functions, the better the coagulation effect.
