摘要
本文研究了用表面活性剂PHOMAC作增敏剂,邻硝基苯基荧光酮(O—NPF)为显色剂光度测定微量铬的新方法.二十余种阴、阳离子共存时,不影响微量铬的测定,本法可用于矿物中微量锆的测定,结果满意.
Spectrophotometric determination of trace zirconium with the O-NPF and PHOMAC are studied. The new method of spectrophtometric determination of Zr has been established. It can be applied to the direct determination of trace Zr in minerals.
