- 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 abaoxibance at 545 nm was measured by uv 一 visible spectrophotometer. Hie 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 far the determination of quaternary aramotiium salt content in disinfector.
