锑锭、氧化锑、硫化锑 (简称锑产品 )是我国大宗出口产品之一。锑产品中微量硒的测定 ,通常采用砷作载体、苯浮选分离、硒试剂光度法测定 [1,2 ] ,该方法操作繁杂 ,砷和苯毒性大 ,环境污染严重。如采用极谱法、ICP- AES法、冷原子吸收法测定 ,则由于存在大量锑基体干扰 ,也不宜
Antimony ingots, antimony oxide, antimony sulfide (referred to as antimony products) is one of China’s bulk export products. Antimony products trace selenium determination, usually arsenic carrier, benzene flotation separation, selenium reagent spectrophotometry [1,2], the method of complicated operation, arsenic and benzene toxicity, serious environmental pollution. If polarographic method, ICP-AES method, cold atomic absorption spectrometry, due to the presence of a large number of antimony matrix interference, it is not appropriate
