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。
In this paper, the performance and mechanism of CL-P_ (350) adsorption scale from nitric acid solution are reported.The experimental results show that the adsorption equilibrium obeys the Langmuir empirical isotherm, and the adsorbate molecule The molar ratio of P (350) to Re (Ⅶ) was 2: 1.Re (Ⅶ) was adsorbed on the resin in the form of adsorption. The adsorption mechanism was integrated and the thermodynamic function of adsorption was determined.
