摘要
研究了溶液ｐＨ值对三苄胺浸渍树脂吸附铂的影响、交换速率和交换容量等分析特性，并且在柱操作条件试验基础上确定了三苄胺浸渍树脂柱吸附－原子吸收测定铂的方法。本法用于测定铂催化剂中微量铂，取得较好结果。
The characteristics of tribenzylamine (TBA) impregnated and its analytical application are investigated. The pH effect on platinum adsorption,the adsorption rate, and the applicable ,micro-column conditions forplatinum ion on TBA resin are measured and tested by flame atomic absorption spectrometry. Based on dynamic* testing the method has been used for the separation on TBA resin and the determination of trace platinum in plati-* num-catalyst by AAS.
