A novel determination method of Ag+ was established. In acetic acid-sodium acetate buffer (pH 5.0) medium, Ag+ reacts with SCN- to form AgSCN in the presence of TritonX-100, which results in an increase of resonance light scattering (RLS) and giving a new RLS spectrum. The maximum RLS peak was at 585 nm. The enhancement of resonance light scattering at 585 nm was proportional to the concentration of Ag+ ranging from 0.0045-4.00 μg mL-1 (r=0.9991), and the detection limit was 1.37 ng mL-1 with the recovery of 97.70%~104.80%.
