摘　　要：利用氯化银沉淀在明胶 乙醇水溶液中的稳定性,建立了一种新的测定有机物工艺水中微量氯离子的分光光度法.其λmax=300nm,线性范围为0～6mg/L,吸收曲线为C=-0.00289+1.2164A,回收率为95.2%～101.3%.作者提出的水样中微量氯离子浓度测定的实验微型化具有理论上定量分析的可行性,同时也可在实际中应用.Using the stability of silver chloride sediment in the gelatin-alcohol water solution, the author presents a new spectrophotometry to determine trace chlorineion in technology water including organic matter. In this method, λ_(max) = 300 nm,the linear scope lies between 0 and 6 mg/L, the absorption curve is C=-0.002 89+1.216 4 A,and the rate of recovery lies between 95.2% and 101.3%. This experiment microminiaturization is feasible in quantitative analysis and also necessary in practice.
