摘要
1引言铜精矿中通常会含有硒杂质,其存在量直接影响电解铜的过程。成品黄铜中硒的含量对其性能有重要影响,硒的含量太高,则降低了黄铜铸件的耐蚀性、强度、硬度和切削性等[1]。近年来，原子荧光光谱法测定硒以其灵敏度高、干扰少等优点受到分析工作者的重视。目前，铜样及矿石样品中硒的测定多采用分离富集的方法，
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%.
