| description | The invention discloses a method for determining inorganic anions in salt products. Standard solutions of fluorine ions, sub-nitrite ions, nitrite ions, phosphate ions, sulfate ion are separately removed and sequentially subjected to sample injection from low concentration to high concentration under the set instrument operating conditions, and a standard working curve is drawn by taking the ion concentration as the x-coordinate and taking the corresponding chromatographic peak area as the ordinate; carbonate eluents are added to samples, water bath ultrasound is carried out until the samplesare dissolved completely, a test solution is treated by a silver ion exchange resin column and then the outflowing solution is treated by a hydrogen ion exchange resin column, carbonate eluents are added for constant volume, even mixing is carried out, filtering is carried out through a filter membrane for standby application, a sample solution is removed and measured by injecting an ion chromatograph under set instrument |
