摘要
采用氧弹为样品燃烧器,NaOH溶液为燃烧产物吸收剂,氢化物-原子吸收光谱法测定了硫磺中的砷。线性范围为0.5-50.0μg·L-1;检出限为0.019μg·L-1;回收率达97.8%-101.7%。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,absorbed with 2. 5mol/L NaOH solution,and determined directly by HG-AAS. The linear range is 0. 5-50. 00μg·L-1. The detection limit is 0. 019μg·L-1 and the recoveries are in the range of 97. 8%-101. 7%. The method is simple, convenient and pollution-free. The accurate and precision meet the needs of analysis.
