摘要
研究了以过氧化氢为氧化剂 ,硝酸 -甘油为介质 ,氯化银浊度法测定工业亚磷酸中氯离子的试验条件。本系的稳定性高 ,分析条件易于控制。测定波长为 380nm ,氯离子含量在 50～ 30 0 μm/ 50ml范围内呈线性关系。本法具有简单、快速、准确的优点 ,用于工业亚磷酸中氯离子的测定中结果令人满意。
The experimental condition was studied for the determination of chloride from industrial grade phosphorous acid with perhydrol oxidation and nitric acid-glycerin medium,and by silver chloride turbidimetry.The stability of the system was high and controlling of the analytical condition was easy.The selected wavelength wass 380nm,the linear range of the concetration is from 50 to 300μg/50ml.The method were simple,rpaid and accurate.
