摘要: 聚丙烯酰胺(PAM)具有强极性,对硅胶等极性固体表面具有强烈的吸附作用,陈九顺等[1]用4%的NaCl水溶液为淋洗液和Adamson[2]用0.1mol/L的吗啡啉水溶液为淋洗液虽能部分解决硅胶担体对PAM样品的吸附,但他们对吸附的实质问题未进行研究,PAM等高分子化合物在固体表面上的吸附问题的研究尚处于初级阶段[2]

Abstract: In this work an analytical measurement method was established for determining PAM adsorption isothermal curves in the extremely diluted solution, diluted solution and relatively concentrated solution respectively. The adsorption mechanism was also investigated preliminarily. The effects of several organic compounds and an inorganic salt (NaNO3) as the adsorption inhibitors on the adsorption of PAM on the surface of silica gel were studied. The results indicate that (1) PAM is strongly adsorbed on the surface of silica gel; (2) aminoethyl alcohol, morpholine and sodium nitrate are effective adsorption inhibitors.
