摘要: Reduction in 1 M H(2)SO(4) with liquid zinc amalgam and extraction isopentanol from 3M H(2)SO(4), separates rhenium almost all the interfering elements of importance determination. The small amounts Mo, U, Fe Ru still accompanying are removed by thiocyanate-pentyl acetate or oxine-chloroform extraction. method is simple, rapid very wide applicability. It particularly useful determination various alloys tungsten-containing samples.
