| Abstract: | This paper discusses the method of the rapid determination of the content of gold in blister copper by flame atomic absorption spectrophotometry, samples is dissolved in aqua regia, and the gold is absorbed with polyether foam plastics, then the absorbed gold is reliefed with thiourea. This method is simple, rapid, accuracy and suitable for the rapid determination of blister copper, and the recovery rate was in the range of 95.0%~105.0%, the result is satisfactory. |
