【摘要】 本文研究了盐酸体系中ＣＬ－７４０２萃淋树脂吸附钯的性能与机理。结果表明：在ｐＨ＝２的２ｍｏｌ．１￣－１ＨＣｌ介质中，树脂能迅速、定量地吸附钯，其吸附容量可达２８．７０ｍｇ．ｇ￣－１（干树脂）。树脂对钯的等温吸附式符合Ｑ＝Ｋ．Ｃ；测得吸附热为ΔＨ＝－５．６２ｋＪ．ｍｏｌ￣－１，升高温度对吸附不利。用斜率法确定反应机理为：更多还原

【Abstract】 The properties and mechanism of CL- 7402 resin for extracting palladium(Ⅱ)from hydrochloric acid solution is studied in this paper. The experimental results indicate that theextraction is an anion exchange process PdCl The absorption capacity is 28. 70 mg/g￣-r. The absorption processcan be expressed with formulaThe influence of temperature on the extraction of PdⅡ)is also discussed,The enthalpyof extraction, H,is-5.62 kJ/mol.更多还原
