GB/T 23991-2009 "Determination of Soluble Harmful Element Content in Coatings" specifies the test methods for the content of soluble harmful elements such as lead, cadmium, chromium, and mercury in coatings, and is applicable to various types of coating products. After extraction with an extraction solution of a specific acidity, the element content is determined using an atomic absorption spectrophotometer or an inductively coupled plasma emission spectrometer. The detection requires instruments such as an atomic absorption spectrophotometer, ICP spectrometer, constant temperature oscillator, and analytical balance, providing a basis for the safety and environmental quality control of coating products.
