摘要
研究利用火试金法预富集得到合粒,合粒经王水溶解后用电感耦合等离子体发射光谱法检测Pt、Pd含量,此方法具有简单、准确、迅速等特点。研究结果可以看出,采用本方法检测硝酸氧化炉灰及催化剂中的铂、钯含量,不但消除了电感耦合等离子体发射光谱法(ICP-AES)直接测定带来的基体干扰,而且试验结果稳定,精密度良好。
The study used the fire assay method to pre-enrich the granules. The granules were dissolved in aqua regia and the content of Pt and Pd were detected by inductively coupled plasma emission spectrometry. The method is simple, accurate and rapid. It can be seen from the results that the method of detecting the platinum and palladium contents in the nitric acid oxidation furnace ash and the catalyst not only eliminates the matrix interference caused by the direct measurement of inductively coupled plasma optical emission spectrometry (ICP-AES), but also the test results are stable, the precision is good.
