摘要
介绍了顶空氢化物火焰原子吸收法测定铜精矿中锑的方法,讨论了锑测定的最佳条件,方法的灵敏度为0.02μg,相对标准差(n=8)5.4％,标准加入法的回收率为84.4％～93.5％。
The headspace-hydride method for determination of antimony in cupper concentrates by flam atomic absorption spectrometry was developed. The optimal conditions for the determination of antimony were studied. The sensitivity is 0. 02, the relative standard deviation(n = 8)is 5. 4% ,the recovery of standard addition is from 84. 4% to 93- 5%.
