| Abstract: | The reaction between copper(Ⅱ) and PICPA was sensitive at pH 8.5 in the presence of OP and hydroxylamine hydrochloride. In the present report, the spectral correction principle was applied in the determination of properties of the Cu- PICPA complex instead of the ordinary spectrophotometry because of the absorption effect of the excessive PICPA. Results showed that the complex was expressed as Cu(PICPA)2, its cumulative stability constant K = 7.11 ×1011(temperature 15 ℃ and inoic strength 0.1M) and its real absorptivity ε = 5.58 × 104L. mol- 1. em- 1 at 620nm. |
