摘要
试样经火试金法处理后 ,将所得贵金属颗粒用硝酸溶解 ,加入适量的盐酸赶尽硝酸 ,然后在 8mol/L的盐酸介质中用石油醚 -三氯甲烷溶液萃取 ,以DDO为显色剂进行钯的光度法测定。
The noble metal granules obtained after fire assaying of sample was dissolved in nitric acid,and adding hydrochloric acid appropriately to drive away nitric acid,then extracting Pd in 8mol/L medium of hydrochloric acid by petroleum aether-chloroform solution.The palladium was determined by photometry with DDO as the color reaction indicator.
