摘　　要：研究了水溶性有机高分子(OP)与聚合硫酸铁(PFS)的复配特点,从分子结构和溶剂化角度探讨了OP在PFS中的稳定机制,并采用FT-IR、SEM和X射线衍射探讨了OP与PFS的相互作用.结果表明:具有吡咯环结构的聚二甲基二烯丙基氯化铵、聚二乙基二烯丙基氯化铵和聚乙烯吡咯烷酮能与PFS复配,且具有较好的稳定性;OP与PFS形成了互相融合的复合体系,主要与PFS中Fe4.67(SO4)6(OH)2.20H2O物相发生相互作用.The composite characteristics of water-soluble organic polymer （OP） with polyferric sulfate （PFS） were studied. The stabilization mechanism of OP in PFS solution was discussed in terms of molecular structure and solvability, and the interactions of OP with PFS were investigated by using FT-IR, SEM and X-ray diffraction. The results show that the homopolymers of dimethyldiallylammonium chloride, diethyldiallylammonium chloride, and polyvinyl pyrrolidone with pyrrole ring structure can com- bine with PFS well with good stabilities. The stable composite flocculants are fusing systems, and OP mainly interacts with the main phase Fe4.67（SO4）6（OH）2·20H2O of PFS.
