| titleOfInvention | Purification process of ultrapure acid liquid |
| abstract | The invention belongs to the technical field of ultrapure acid liquid purification, and particularly relates to a purification process of an ultrapure acid liquid. The invention provides a purification process of ultrapure acid liquid, which comprises the following steps: (1) an adsorption process: uniformly mixing industrial acid liquid and an adsorbing material in a nitrogen atmosphere, stirring at 50-90 ℃ for 2-4 h, and cooling to 10-15 ℃; (2) and (3) membrane filtration process: the mixed solution obtained by cooling flows through a filter membrane at room temperature, and the obtained filtrate is collected; (3) and (3) rectification process: rectifying the filtrate in a rectifying tower; (4) monitoring and analyzing: and collecting the fraction obtained by rectification, and monitoring the content of heavy metals in the fraction. |
