Embodiment 1
[0041] H of volume D + Type 001×7 strong acidic cation exchange resin is vacuum pumped into the high-efficiency TOC cleaning machine 1, and 15 megohm ultrapure water with a volume of 2D is added to the TOC high-efficiency cleaning machine 1 for cleaning for 1 hour, and the water filter is turned on after cleaning Valve, drain the cleaning solution, and add ultrapure water with a volume of 2D into the TOC high-efficiency cleaning machine 1, turn on the TOC high-efficiency cleaning machine 1 for stirring, open the vacuum valve on the hydrogen-type transformation column 2, and vacuum the positive resin Pumped into the hydrogen-oxygen transformation column 2, the volume of 2D hydrochloric acid with a mass fraction of 2% is added dropwise into the hydrogen-oxygen transformation column 2 through the hydrochloric acid head tank 4 for transformation; The 15 megohm ultrapure water is washed to neutrality. After the washing is completed, the nitrogen valve on the hydrogen-oxygen transfo...
