When the titration determination of the active matter content in water treatment agent dodecyl dimethyl benzyl ammonium chloride (1227) is conducted according to the present industrial trade standard,the liquid phase is easy to agglomerate,and thus,difficult to judge the end-point of titration. Furthermore,the measured value of the active matter content is on the low side. It is found that increasing the temperature of sample solution can improve the agglomeration remarkably in the course of determination,and adding adequate dispersant can decrease the agglomeration and make it easier to make judgement. The results show that the improvement obtained increases the accuracy of the analytical results,providing reference for standard recension.
