摘　　要：研究了聚丙烯酸-丙烯酰胺树脂对罗丹明6G染液的吸附性能。探讨了树脂的结构、吸附时间、罗丹明6G染液的初始浓度、树脂的用量、溶液的pH值以及离子强度对吸附性能的影响,并对吸附结果进行热力学和动力学拟合。结果表明:吸附过程热力学较好地符合Freundlish方程,动力学模型符合准二级动力学方程,且相关系数较高。The adsorption of Rhodamine 6G on poly（acrylic acid-co-acrylamide） resin was studied. The factors influen cing adsorption performance such as the structure of the resin,absorption time,initial concentrations of Rhodamine 6（;,dosage of adsorbent, pH value of dye solution and ionic strength were discussed. The findings include the follo- wing：the adsorption results conform to adsorption thermodynamics and kinetics, the adsorption thermodynamics agrees with Freundlish equation, the kinetics agrees with pseudo-second-order equations and the correlation coeffi eients were comparatively high.
