摘要
通过对工业硫磺中汞含量测定时载流液种类、硼氢化钾浓度、消解条件的选择优化,建立微波消解-原子荧光分光光度法测定工业硫磺中的Hg含量的方法.该方法测定浓度范围 0～5μg/L的含汞样品线性相关系数大于 0.999,汞的RSD小于 4.5%,加标回收率在 100.00%～113.50%,具有快速、简便、准确的特点,可以为硫磺的下游制造业业筛选原料提供技术参考.
Abstract
This article establishes a method for deter mining the mercury content in industrial sulfur using microwave digestion atomic fluorescence spectrophotometry by opti mizing the selection of carrier fluid type,potassiu m borohydride concentration,and digestion conditions.This method has a linear correlation coefficient greater than 0.999 for mercury containing sa mples with a concentration range of 0～5 μg/L,a mercury RSD of less than 4.5%,and a spiked recovery rate of 100.00%～113.50%.It is fast,si mple,and accurate,and can provide technical reference for screening raw materials in downstrea m sulfur manufacturing industries.
