Problems solved by technology

[0003] Ion chromatography is a conventional method for detecting trace anions at present. It has the advantages of fast analysis speed, high separation ability, simple method, and simultaneous analysis of multiple components. However, it can only be used to determine trace anions in aqueous solutions and water-soluble organic compounds. , cannot detect trace anions in water-insoluble solid compounds such as barium carbonate

Abstract

The invention discloses a barium carbonate electrolytic dissolving device, which can dissolve barium carbonate through electrolysis, so that it can be combined with ion chromatography to measure trace anions. The electrode chamber and the cation exchange membrane, the anion and yang chambers are composed of two corrosion-resistant films and the space between the cation exchange membranes, and the anode chamber has a sample pool. The invention also discloses a detection method of the barium carbonate electrolytic dissolution device. The invention avoids the introduction of impurity ions by direct electrolysis instead of conventional acid dissolution, and can directly inject samples after the samples are dissolved, and can realize the detection of trace anions in barium carbonate, thereby expanding the application range of ion chromatography. Moreover, using water as the electrolyte solution is cleaner and pollution-free, and the post-processing is also more convenient.

Description

technical field [0001] The invention relates to a treatment device for the water-insoluble solid compound barium carbonate, more specifically a device for realizing the dissolution of the barium carbonate by electrolysis so as to be able to measure trace anions in combination with ion chromatography. Background technique [0002] Electrolysis technology is a technology that uses the electrochemical reaction of the battery principle to process. It has the advantages of high efficiency and good surface quality in processing. Electrolysis is currently mostly used in the fields of metallurgical industry, sewage treatment, electroplating and polishing, and also in the field of ion chromatography. Combined use, such as eluent generator and post-column derivatization device, but not yet applied to the pretreatment part. [0003] Ion chromatography is a conventional method for detecting trace anions at present. It has the advantages of fast analysis speed, high separation ability, s...
