This standard describes methods for determining the mercury content in caustic soda and caustic potassium, using flameless atomic absorption spectrometry for liquid and solid samples. The test methods include direct analysis and acid reducing agent analysis, with detection limits of 0.1 ppb and 0.01 ppm, respectively. The standard emphasizes the toxicity of mercury and requires users to refer to the relevant safety data table during use to ensure the safety of operation.
