| Abstract: | A rapid and accurate method for determination of F-, Cl-, SO42-, NO3- in sodium dihydrogen phosphate by ion chromatography with suppressed conductivity detection was established.After simple dissolution treatment, the samples can be analyzed directly by the chromatography instrument with an analysis time of less than 30 minutes.The experimental results showed that the method had good reproducibility, high sensitivity and simplicity and can be applied for determination of other industrial raw materials, such as sodium phosphate, calcium hydrogen phosphate, phosphoric acid, and so on. |
