Method for treating tetraalkylammonium ion-containing liquid |
| abstract |
PROBLEM TO BE SOLVED: To prevent cation exchange resin or chelate resin from undergoing contact treatment with a tetraalkylammonium (TAA) ion-containing liquid and causing the resin to crack and deteriorate early even if the regeneration cycle is repeated. To do. A TAA ion-containing liquid having a TAA ion concentration exceeding 0.15% by weight (for example, a photoresist developing waste liquid) using at least one of a strong acid cation exchange resin, a weak acid cation exchange resin, and a chelate resin. ), Or when recovering water after adsorbing and removing TAA ions from the TAA ion-containing liquid using at least one of a strong acid cation exchange resin and a weak acid cation exchange resin. The TAA ion concentration of the TAA ion-containing liquid that is initially passed after the regeneration of the resin and the resin is reduced to 0.15% by weight or less and brought into contact with the at least one resin to adsorb the TAA ions. [Selection figure] None |
