Abstract
An automated method has been developed to determine arsenic and lead in pre-treater, reforming and other catalysts using microwave digestion and atomic absorption spectrometry with electrothermal atomisation. The proposed method is precise and accurate with a practical lower limit of determination in the catalyst of 10 mg kg–1 for arsenic and 5 mg kg–1 for lead.Keywords
