Determination of contaminated heavy metals on catalytic cracking catalysts by XRF spectroscopy and Compass300

An analytical method for the determination of contaminated heavy metals Fe,~ 안에,V,구리,Sb and Ca on the balance catalyst of catalytic cracking was developed based on Compass portable X-ray fluorescence spectrometry. Various factors affecting the determination of Fe,Ni and other elements were investigated. The carrier for preparing standard samples with fresh catalyst was proposed, which overcame the influence of mutual interference between elements and reduced the influence Matrix effect, the accurate results of Fe,Ni and other elements were obtained. The experimental results show that XRF spectroscopy is a fast, accurate and simple analysis method to determine the content of contaminated heavy metal elements on the catalyst
