【Abstract】 The method for determining the content of compound quaternary ammonium disinfectant and its titration error analysis were investigated. The influence of color change at the end point of titration and preparation of four benzene boron sodium standard solution were explored,and the mono quaternary quantitative analysis methods were compared. The results revealed that the four benzene boron sodium two-phase method was suitable for quantitative analysis of compound quaternary ammonium salt,but attention should be paid to the preparation of four sodium benzene standard solution and the determination of the color change at the end point of titration.更多还原
