摘　　要：研究了部分水解聚丙烯酰胺(HPAM)溶液中,多价金属离子与大分子之间的络合现象.在有络合物生成的范围内,通过实验,计算得出了Cu2+、Zn2+离子与HPAM形成络合物时的配位比和络合常数,以及Cu2+离子和HPAM配位比随HPAM的水解度改变的变化规律.The complex between metal ion and macromolecular in HPAM solution has been studied. Within complex being producted, coordination number and coordination constant have been calculated when Cu2+ and Zn2+ complex with HPAM. The effect of HD on coordination number has also been studied.
