A COMPARATIVE STUDY ON KINETICS OF ION EXCHANGE IN BINARY SYSTEM FITTED BY THREE MODELS$$$$SONG YINJIE;ZHAO AIMIN（Department of Modern Physics, Lanzhou University,730000）ABSTRACT A"three-necked flask"technique is employed for the study of the kinetics of H~--UO ionexchange system with strong acidic cation exchange resin.

文章以强酸性阳离子交换树脂作交换剂，用三颈瓶法研究了H￣＋UO￣＋离子交换反应动力学。

The results show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.

研究结果表明：甲基的取代可增强阳离子的静电作用能力，同时，削弱它与矿物表面之间的氢键作用；苄基的取代不仅增强药剂的静电效应，而且增加氢键的结合能力；理论分析结果与浮选试验结果一致，季铵盐的浮选能力较伯胺与叔胺的强，连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强，且受pH值影响小。
