Abstract:In the industrial production of zinc hydrometallurgy，the zinc containing solution has high salinity and low acidity，and the analysis results of various elements are greatly affected by temperature. The contents of Fe，Co，Cd，As，Sb and Zn are relatively high，and it is difficult to remove impurities in the process，which has a significant impact on production. When these elements are analyzed，their results also fluctuate greatly with the change of temperature. Thus，it is significant to study their fluctuation rules and determine the optimal temperature conditions for analysis. When studying the fluctuation law，take large samples first while they are hot，and then divide them in small bottles. Then，in the range of 12~80 ℃，take 5~10 ℃ as a step，and measure each analysis item at different temperatures by volumetric method，dual channel atomic fluorescence spectrometry and inductively coupled plasma atomic emission spectrometry. According to the measurement results，the optimal analysis temperature is 60 ℃.
