| Abstract: | A new method is introduced to determine the mercury, namely by means of flame atomic absorption spectrometry of dual-capillary spray-hydride generation, i. e, mercury in concentrated ore of ZnS is determined from 0.00X% to 0. X% in the medium of 5% HCl （with a certain amount KBH4, thiourea, ascorbic acid） , and X mg/L of mercury in sulfuric acid products is determined in medium of 4% HESO4 （with a certain amount KBH4 , thiourea, ascorhic acid） too. The proposed method is fast, simple, accurate, and standard sample recovery is 90% - 110% , which can be used for monitoring analysis of trace mercury in production process of hydrometallurgy zinc and sulfuric acid, the results are perfect. |
