电感耦合等离子体质谱法(ICP-MS)测定活性炭中19种杂质元素含量
|
摘要
活性炭经马弗炉950℃灼烧完全灰化,加3 mL王水、2 mL HF、2 mL HClO4分解灰分,加入5 mL(1+1) HCl加热溶解盐类,建立了电感耦合等离子体质谱法测定活性炭中19种杂质元素含量的分析方法。在优化的实验条件下,方法的定量限在0. 007～0. 060μg/g之间,加标回收率在88. 0%～112. 0%之间,与直流电弧光谱检测结果基本一致。结果表明,该方法可以满足高纯度活性炭中多种杂质元素同时、快速、准确测定的需求。
The activated carbon was fully ashed in the Muffle furnace under 950℃,and the ash was dissolved by 3 m L aqua regia,2 m L hydrofluoric acid and 2 m L perchloric acid. The salts in the ash was dissolved by 5 m L( 1 + 1) HCl heating on a hot plate. Based on it,an analytical method was built to simultaneously determine 19 impurity elements in activated carbon by inductively coupled plasma mass spectrometry. Under the optimized conditions,the detection limits for target elements were 0. 007-0. 060 μg/g. The recoveries for target elements were between 88. 0% and 112. 0%. The result was basically consistent with that obtained by direct current arc spectrometry. The result showed that this work could meet the analytical requirements for quick and accurate determination of multiple impurity elements in high purity activated carbon.
