该方法用于测定新鲜和废无硅氧化铝催化剂中钯的含量，范围约为0.2至1质量-%。铂和铱等组分与碘化物产生有色离子，并在约408 nm处吸收，构成干扰，因此无法分析含有此类组分的催化剂。

This method is for determining palladium in fresh and spent silica-free alumina catalyst over a range of approximately 0.2 to 1 mass-%. Components, such as platinum and iridium, that produce colored ions with iodide and absorb at approximately 408 nm constitute an interference and, therefore, catalysts that contain such components cannot be analyzed.
