The enhancement of the oxidation of luminol by K2 S2 O8 is studied by the complex AuR + 2 formed by 8-hydroxyquinoline (HR) and Au (Ⅲ). Based on this, a new chemiluminescence method for the determination of gold is established. The results showed that the detection limit of Au (Ⅲ) was 8 × 10 -11 μg / L and the response curve of working curve was in the range of 1 × 10 -9 ~ 1 × 10 -7 μg / L. When the concentration was 1 × 10 -7 μg / The RSD of LAu (Ⅲ) ions was 2.0%. The results of the chemiluminescence detection of trace amounts of gold in the single crystal lattice of silicate gave better analytical results
