摘要
本文以新显色剂磺胺偶氮氯膦建立了微量钯的新的直接和流动注射分光光度法。方法简便、快速,具有良好的选择性。在数十倍贵金属离子共存的情况下可不经分离直接在水相测定矿石中的微量钯。
New methods for spectrophotometric and flow injection analysis determination of Pd(Ⅱ) have been established using 1,8-dihydroxy-2-[(4-chloro-2-phosphonic phenyl)-azo]-7-[(4-sulphonic acid amide phenyl)-azo]-3,6-disulphonic acidic naphthalene as a colour reagent.The methods are selective, rapid and simple. when Pd is determined,no separation is needed.The methods can be used to determine Pd in ore,and good results are obtained.
