Non-targeted DGT adsorption film for enriching multiple types of new pollutants as well as preparation method and application of non-targeted DGT adsorption film

The invention discloses a non-targeted DGT adsorption film for enriching multiple types of new pollutants as well as a preparation method and application thereof. The preparation method comprises the following steps: S1, purifying and activating resin raw materials, wherein the resin raw materials comprise WAX resin and MCX resin; s2, preparing an adsorption film solution: taking WAX resin and MCX resin, adding the WAX resin and the MCX resin into the cross-linking agent solution, then adding an initiator and a catalyst, and uniformly mixing; s3, gel preparation: injecting the adsorption film solution into a gel forming model, and standing until the solution is solidified into a gel film; and S4, washing the gel film until the pH is neutral. Compared with other single resin materials, the non-targeted DGT adsorption film has the advantages that the pollutant adsorption type range is larger, the non-targeted DGT adsorption film can be used for measuring the concentration of cationic, anionic, neutral and ampho
