摘要
采用氧弹为样品燃烧器,NaOH溶液为燃烧产物的吸收剂,使用氢化物-原子吸收法测定了硫磺中的砷。方法的线性范围为0.5-50.0μg·L-1;检出限为0.019μg·L-1;回收率迭97.0％-104.0％。方法快捷、简便易行,无污染,准确度和精密度均能满足试样分析要求。
The samples were combusted in the oxygen bomb and were absorbed by 2.5mol/L NaOH solution. The absorption solution was determined directly by HG-AAS. The linear range is 0.5-50.00.019μg·L-1; the detection limit is 0.019μg·L-1 and the recoveries is 97.0%-104.0%. The results showed that this method is simple, convenient and pollution-free. The accurate and precision can satisfy the needs of analysis.
