【摘要】 本文报道四甲基膦酸二甲庚酸萃淋树脂（ＣＬ－Ｐ＿（３５０）从硝酸溶液中吸附鳞的性能和机理研究。实验结果表明，吸附平衡服从Ｌａｎｇｍｕｉｒ经验等温式。测得吸附物分子中Ｐ（３５０）与Ｒｅ（Ⅶ）的摩尔比为２：１。Ｒｅ（Ⅶ）是以形式被树脂吸附，其吸附机理属于综合反应：并测定了吸附过程的热力学函数。更多还原

【Abstract】 The property and mechanism of adsorpting rhenium from aqeous nitric acid was reported by using methyl phosphorous acid dimethyl heptyl ester levextrel resin(CL-P₃₅₀).Experimental results showed that the adsorption of the resin for Re（Ⅶ）can be de scribed by Langmuir’s equation of the equilibrium State. By means of Chemical analysis,the molar ratio of P₃₅₀ to Re（Ⅶ）in the adsorption molecular determined was 2:1.IR analysis in-dicated that ReO was taren up by ionic association mechanism:and the therimodynamic functions in the adsorption process of ReO have been determined.更多还原
