摘　　要：在硝酸和Triton X-100介质中,氯化物能与硝酸银定量反应生成稳定的氯化银纳米微粒,存在共振散射效应。Cl-的浓度在0.071～5.325μg/mL范围内与共振散射强度(IRS)成较好的线性关系。检出限为0.034μg/mL,用于纯净水中氯化物含量的测定,具有简单、快速、灵敏度高等特点,结果满意。In nitric acid and Triton X-100 medium, chloride can react quantitatively with silver nitrate to stable silver chloride nanoparticles, which exhibit resonance scattering effect. The scattering intensity at 495 nm was linear to Cl^- concentration in the range of 0.71-5.325 μg/mL.. The detection limit was 0.034 μg/mL. The method had been applied to determination of chloride content in pure water, with sensitivity, simplicity, reproducibility and satisfactory results.
