摘要：
In pH 4.2 HAc-NaAc buffer solution, hydroxylamine hydrochloride reduced Cu2+ to Cu+ that coordinate the nitrogen atom of 1,2,3-benzotriazole (BTA) to form Cu-BTA complex particles with a resonance Rayleigh scattering (RRS) peak at 369 nm. Under the selected conditions, when the BTA concentration increased, the RRS intensity at 369 nm increased. The increased RRS intensity Delta I-369nm was linear to BTA concentration in the range of 0.17-13.36 mu g/mL, with a regression equation of Delta I-369nm = 89.91C + 96.7, and the detection limit is 0.17 mu g/mL. Accordingly, a new RRS method for BTA was established.
