| titleOfInvention | Amino polycarboxylic acid porous material and preparation method and application thereof |
| abstract | The invention provides an aminopolycarboxylic acid porous material and a preparation method and application thereof, wherein the preparation method comprises the steps of dispersing rigid particles in an aqueous solution of polyethyleneimine, adjusting the pH value, and adding an oil phase under stirring to obtain an oil-in-water emulsion; adding a cross-linking agent into the oil-in-water type emulsion for cross-linking, deoiling, dehydrating and drying to obtain a porous material; adding the porous material into an aqueous solution containing halogenated acetic acid to react under an alkaline condition to obtain an aminopolycarboxylic acid porous material; when the porous material is used as an adsorbent, the porous material can be regenerated by adjusting the pH value, and generally adsorbs organic anions at a low pH value and desorbs the organic anions at a high pH value; adsorbing organic cations at a high pH value and desorbing at a low pH value; the adsorption of metal ions is carried out near neutrality, and the metal ions can be regenerated under the condition that the pH value is 1-3; compared with the prior art, the aminopolycarboxylic acid porous material has the characteristics of large size, higher mechanical strength, easy regeneration, easy separation and the like. |
