摘要
本文系统研究了金的快速分离富集,建立了以Br_(2)、NaCl、HNO_(3)混合溶液消解矿样,TBP树脂分离富集和TMK显色光度法测定的新方法。本法简便、快速,用于分析0.01~200g/t不同含金量的矿样,结果令人满意。
A systematic study for high speed separation and preconcentration of goid with a-TBP reain has been described.The ores are dissolved by a mixed solution of 10%Bn-50%Naa(30%)and 40%HNOs.This metbod is simple and apid,and has been used for the detemination of glod in ors Satisfactory results have been obtained with detaction for gold of 0.01 to 200g/1.
