[0190] The rest of the steps are the same. In step (6) the zinc smelting acid leaching slag sample treatment process, when the concentration of the element to be measured in the zinc smelting acid leaching slag sample is lower than 0.10ug / mL, before the zinc smelting acid leaching slag sample solution is fixed to volume , Adding the corresponding element standard solution to make the concentration of the element to be tested in the zinc smelting acid leaching slag sample reach 0.50ug / mL. The concentration of the element to be tested in the zinc smelting acid leaching slag sample is subtracted from the concentration introduced by the added standard solution, and then according to the step ( 7) Calculate the analysis results. Among them, the effect of adding the corresponding element standard solution to the zinc smelting acid leaching residue sample is to improve the accuracy of the analysis result.
