在 0 0 4mol/LH2 SO4- 0 3%Triton -X介质中 ,Ag(Ⅰ )被紫外光光还原形成银溶胶 ,于 450nm处产生一灵敏的共振散射峰 ,Ag浓度在 0 1～ 4μg/ml与共振散射光强度呈良好线性关系 ,方法的检出限为 0 0 5μg/mlAg。实验结果表明 ,该法用于废水中银的测定具有简便、快速等特点。
In 0 0 4mol / LH2 SO4- 0 3% Triton-X medium, Ag (Ⅰ) was reduced by UV light to form silver sol, which produced a sensitive resonance scattering peak at 450nm with Ag concentration of 0 1 ~ 4μg / ml The results showed that the detection limit of the method was 0 0 5μg / mlAg. The experimental results show that the method for the determination of silver in wastewater has the characteristics of simplicity and rapidity.
