柠檬酸对聚硅酸聚合氯化铁的制备及性能影响

Citric acid effect on the preparation and preperties of polysilicic acid-polyferric chloride flocculant

柠檬酸加入到聚硅酸聚合氯化铁溶液中,对其进行Ferron逐时络合实验、混凝实验、透射电镜实验等,研究其对PSPFC性能的影响,实验结果表明柠檬酸的加入对PSPFC的混凝效果影响显著,浊度显著降低,稳定性得到提高,因此引入柠檬酸根离子是有利的。

When the citric acid is added to the polysilicic acid-polyferric chloride solutions, make time to experiment Ferron complexation marion with time,coagulate experimentation, transmission electriden experimentation, research it＇s effect on the performance on the PSPFC. The re- sult of experiment show that the added of the citric acid can notably effect on the coagulate impact, the turbidity value can notably reduceand the stability is increased,so the added of the citric acid is advantageous.
