| titleOfInvention | A kind of purification process containing citric acid solution |
| abstract | The invention provides a kind of purification process containing citric acid solution, wherein, the method comprises the following steps: (1) will contact with Zeo-karb containing citric acid solution, makes the total concn of metallic cation in the effluent liquid A obtained after contacting be no more than 4ppm; (2) under chromatographic separation condition, described effluent liquid A is incorporated into chromatography column from one end that stationary phase is the chromatography column of resin, make the residual sugar of the citric acid in effluent liquid A and part and other impurity absorption on described resin, then carry out drip washing with eluent, make the residual sugar of part and other impurity and citric acid successively resolve from resin thus citric acid is separated with residual sugar partly and other impurity.Adopt purification process provided by the invention, the citric acid obtained can be made to have higher readily carbonizable substance clearance and citric acid yield. |
