ABSTRACT
OBJECTIVE:
To establish sodium tetraphenylborate volumetric method in place of gravimetric analysis method for the determination of the content of potassium chloride in compound sodium chloride injection.METHODS:
The contents of potassium chloride in compound sodium chloride injection were determined by sodium tetraphenylborate volumetric method and sodium tetraphenylborate gravimetric method respectively,the results of which were compared.RESULTS:
The average recovery of volumetric method was99.75%(RSD=0.46%,n=9),there was no significant difference in the t-test comparison between the determination results of volumetric method and that of the gravimetric method.CONCLUSION:
The sodium tetraphenylborate volumetric method is simple,fast and accurate,which can take the place of gravimetric method for the deter?mination of contents of potassium chloride in compound sodium chloride injection.
