摘　　要：采用核孔膜过滤和动态光散射手段 ,研究了盐度对部分水解聚丙烯酰胺 (HPAM )与柠檬酸铝 (AlCit)交联反应过程的影响以及所形成的交联聚合物溶液线团 (LPC)的大小。结果表明 ,HPAM与AlCit反应所形成的交联聚合物线团对 1.2 μm核孔膜的封堵程度与其反应时间有关。随着NaCl含量的增加 ,交联聚合物溶液 (LPS)对 1.2 μm核孔膜的封堵程度先增加后下降 ,且存在一最佳值。HPAM与AlCit交联后形成的交联聚合物线团尺寸比相同条件下形成的HPAM线团尺寸小 ,并随着盐度的增加而减小。The influence of NaCl content on the size of the linked polymer coils(LPC) and the gelation of partially hydrolyzed polyacrylamide (HPAM) linked with aluminum citrate(AlCit) was studied through nuclepore membrane filtration and dynamic light scattering.Experimental results showed that the plugging degree of the linked polymer coils through the 1.2?μm nuclepore membrane was related to the reaction time.The plugging degree of linked polymer solution(LPS) increased at first and then decreased with the increase of NaCl content,having a optimal value.The size of LPC formed by the gelation of HPAM linked with AlCit was smaller than that of HPAM under the same conditions.The size of LPC decreased with the increase of NaCl content.
