Direct Determination of Nickel in Catalytic-Cracking Feedstocks by Atomic-Absorption Spectrophotometry
Keyword(s):
Nickel in catalytic-cracking feedstocks is determined by atomic-absorption spectrophotometry with no sample preparation other than dilution in p–xylene. A modification of the method of additions permits rapid testing with a detection limit of 0.05 ppm Ni and a precision of 0.05 ppm.
