Abstract
A spectrophotometry method for the determination of low levels of gold(III) with di-2-pyridylketoxime was developed. A stable 2:1 (reagent/gold) water-soluble complex is formed having an absorption maximum at 433 nm and a molar absorptivity of 1.89 × 104. The Beer–Lambert law is obeyed up to 12 p.p.m. The proposed method was applied to the determination of gold in plasma and urine. The method is simple, reproducible, and relatively rapid.
