摘要
Abstract
In the solution with pH =1.0 ~ 2.5,stable blue complex was generted by three bromine azo arsine and yttrium reaction,with maximum absorption wavelength 630 nm.The content of yttrium trioxide was 1 ~20 μ g / 25 mL range,which conformed to the Beer's law.In appropriate conditions,the test did not affect the matrix molybdenum,adding ascorbic acid can eliminate coexisting metal ion interference.Molybdenum yttrium oxide content was determined by this method,which is simple,fast,with satisfactory results.关键词
