本方法用于电感耦合等离子体原子发射光谱法（ICP-AES）测定新鲜二氧化硅催化剂中的钯、金和钾。该方法适用于0.2至1质量%钯、0.1至0.5质量%金和1至5质量%钾的浓度范围。氧化铝含量超过1%的催化剂不能用这种方法进行分析。

This method is for determining palladium, gold and potassium in fresh silica catalyst by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). The method is suitable for the concentration ranges of 0.2 to 1 mass-% palladium, 0.1 to 0.5 mass-% gold and 1 to 5 mass-% potassium. Catalysts containing more than 1% alumina cannot be analyzed by this method.
