Abstract
An inductively coupled plasma atomic emission spectrometry method was developed to determine percent levels of aluminum, cobalt, lanthanum, and ruthenium in fresh, calcined, and spent alumina-based catalysts. Catalysts were digested with 8% H/sub 2/SO/sub 4/ and 10% HCl. Replicate analyses of catalysts of known metals content revealed very good precision and accuracy, percent relative standard deviations for each metal being better than 2%. Results on catalysts are compared to flame atomic absorption spectrometry data for aluminum, cobalt, and ruthenium. Studies showed that no significant interferences existed. 7 tables.
