| Abstract: | This report introduces a novel method to determine the concentration of trace impurities in high-purity sodium hydroxide.The method uses ICP-AES combined with standard addition,thus its accuracy and precision fits the requirement of quantitative measurement.This method has been successfully applied to determine the concentration of calcium oxide(CaO),aluminum oxide(Al2O3) and silicon dioxide(SiO2) in high-purity sodium hydroxide.The method is not only convenient,fast but also very sensitive,therefore is suitable for batch analysis. |
