中文摘要: 建立一种紫外-可见分光光度法测定消毒剂中季铵盐含量的方法。用水溶性曙红Y与季铵盐进行显色反应,使用紫外-可见分光光度计测量其在545 nm处的吸光度。结果表明,季铵盐类消毒剂的线性范围为0.5~5.0 mg/L,相关系数均大于0.999,相对标准偏差小于5%,回收率在97.0%~107.5%之间,该方法快速、准确,适用于消毒剂中季铵盐含量的测定。
Abstract:A uv-visible spectrophotometry method for the determination of quaternary ammonium salt in disinfector was established. The color reaction was carried out with water-soluble eosin Y and quaternary ammonium salt, and the absorbance at 545 nm was measured by uv-visible spectrophotometer. The results show that the linear range of quaternary ammonium disinfector is 0.5~5.0 mg/L, the linear correlation coefficient is above 0.999, the relative standard deviation of the method is less than 5%, and the recovery rate is between 97.0% and 107.5%. The method is fast and accurate, and is suitable for the determination of quaternary ammonium salt content in disinfector.
