摘要
本文建立了分别以5-Cl-PADAB、5-Br-PADAP作为显色剂测定微量钯的流动注射光度分析法,方法简便快速、重现性好,试剂消耗量少。已用于铂、钯二次精矿中钯的测定,结果良好。
Simple and selective FIA methods based on the reactions between Pd and 5-Cl-PADAB or 5-Br-PADAP are proposed. For single determination 100μl of sampl is required. The linear range was found to be 0—3.0μg/ml for 5-Cl-PADAB and 0—7.0μg/ml for 5-Br-PADAP. The determination limit was found to be 0.05μg/ml for 5-Cl-PADAB and 0.10μg/ ml for 5-Br-PADAP. The working capacity is 120 determinations per hour.The methods were applied to the determination of Pd in ores and good results were obtained.
