| titleOfInvention | A kind of polarizing plate waste liquid treatment method |
| abstract | The present invention provides a method for treating polarizing plate waste liquid. The method uses a hydrofluoric acid-containing solution to treat a salt-containing boric acid solution after pretreatment and primary acidification. The potassium fluoroborate product realizes the separation of boron element and inorganic potassium and sodium salts; and can use the hydrofluoric acid waste liquid produced by other industries to treat the salt-containing boric acid solution, which further reduces the waste liquid treatment cost and improves the economic value. |
