PROCESS FOR RECALCITRANT CATIONIC DYEING WASTEWATERS TREATMENT USING GRAPE SEED EXTRACT AND PLANT-DERIVED POLYPHINOLS

摘要

The present invention relates to a water treatment method using a grape seed extract containing a plant-derived polyhydric phenol or a plant-derived polyhydric phenol. Eggplant relates to a water treatment method for removing hardly decomposable cationic dyes. In the present invention, using plant-derived catechins, tannic acid, capperol, gallic acid, quercetin, epicatechin, luteolin, one or more mixtures thereof, precursors, dimers, oligomers, or polymers derived from grape seeds Water treatment takes place.
