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.
