摘要
The authors developed a method in which Dionex “Pre” online sample preparation technique was used to remove chloride by Ag cartridge and Na cartridge. This method is applicable to a wide range of samples and is simpler than off-line approach. The system removes chloride well online for different matrix as analysis grade salt and sodium chloride. The detection limits of bromate, chlorate, chlorite, nitrite, nitrate and sulfate are less than 10 μg/L, and the recoveries are between 80% and 110%. This method holds the advantages of easy-operation, good reproducibility, lower operation cost etc. and is more convenient than off-line approach.
