氢化物发生-原子荧光光谱法测定黄铜中的硒
Determination of Selenium in Brass by Hydride Generation-Atomic Fluorescence Spectrometry
摘要
Abstract
After dissolved in HNO3-HClO4 and the copper matrix was masked with a new nontoxic,pollution free and environment friendly reagent-polyepoxysuccinic acid,the selenium in the brass sample was directly determined without any separation procedures.The method was simple,rapid,accurate,precise and low cost operation.The linear dynamic calibration was 5.0-80.0 μg/L.The detection limit of the method was 0.29 μg/L.The relative standard deviation (RSD,n=11) was 2.4％.The recovery rate with standard addition was 97.5％-104.8％.关键词
