No Sample Preparation

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.

Concentration Limits

Atomic absorption spectrophotometry has been critically evaluated as a method for the determination of traces of arsenic, lead, nickel, and zinc in copper. With careful matrix compensation, reliable (±5%–6%) results were obtained down to lower concentration limits of 0.025% for arsenic, 0.002% for lead, 0.003% for nickel, and 0.002% for zinc. Copper was found to interfere strongly with the determination of nickel in dilute nitric acid solutions. The use of the nitrous oxide—acetylene flame was found mandatory for the determination of arsenic. This work suggests at least limited applicability of atomic absorption to the problem of tracing the origin of ancient copper metal by impurity patterns.
