Determination of mercury content in industrial sulfur by microwave digestion atomic fluorescence spectrophotometry
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.
