摘　　要：为了增强PFS(聚合硫酸铁)溶液的溶解度,提高水处理中混凝反应的效果,通过实验测定了PFS溶液在不同磁化参数下的粘度和表面张力,研究了不同磁化参数下PFS溶液粘度和表面张力的变化特征以及磁场对PFS溶液作用的记忆效应。实验结果表明:随着磁场强度和磁化时间的增加,PFS溶液的粘度和表面张力均会减小;磁场对溶液的作用具有一定的记忆效应,大概10 h左右。在电磁场作用下,PFS溶液的熵值减小,分子间氢键作用增加,磁化后液体有序度增加。In order to enhance the PFS （PFS） solution solubility, improve the effect of coagulation water treatment in PFS solution under different magnetic parameters of viscosity and surface tension were determined by experiment. The memory effect of PFS variation of solution viscosity and surface tension and magnetic field on PFS solution of different magnetic parameter was studied. The experimental results show that the viscosity and surface tension of PFS solution decrease with the increase of magnetic field intensity and magnetization time, and the effect of magnetic field on solution has a certain memory effect, about 10 h. In the alternating magnetic field, reduce the entropy of PFS solution, increase the hydrogen bonding interaction after magnetization liquid more ordered.
