Embodiment 1
[0040] Preparation of anion exchange resin:
[0041] a1) be that the lactose powder that the average particle diameter is 1mm is placed in methyl acrylate and carries out impregnation adsorption 10min, filter out the lactose powder after its impregnation adsorption is saturated;
[0042] a2) Add divinylbenzene to benzene methane to prepare a 16.5wt% reaction solution, add cumene hydrogen peroxide to the reaction solution, the concentration of cumene hydrogen peroxide in the reaction solution is 0.10wt%, and every 100mL 5.5 g of lactose powder adsorbed with methyl acrylate was added to the reaction solution, and placed under stirring conditions to react, and filtered to obtain polymer pellets with a cross-linking degree of 5.5%;
[0043] a3) polymer pellets are placed in water for dipping and dissolving the lactose skeleton and add ferric chloride and chloroethyl ether to carry out chloromethylation reaction, to obtain the chlorinated pellets that the chlorine content is 17wt%;...
Embodiment 2
[0046] Preparation of anion exchange resin:
[0047] a1) the lactose powder that the mean particle diameter is 3mm is placed in methyl acrylate to carry out immersion adsorption 3min, to filter out the lactose powder after its immersion absorption saturation;
[0048] a2) adding divinylbenzene to benzene methane to prepare a 18wt% reaction solution, adding cumene hydrogen peroxide to the reaction solution, the concentration of cumene hydrogen peroxide in the reaction solution is 0.10wt%, and every 100mL reacts 6g of lactose powder adsorbed with methyl acrylate was added to the liquid, and placed under ultrasonic vibration to react, and filtered to obtain polymer pellets with a cross-linking degree of 5.0%;
[0049] a3) adding ferric chloride and chloroethyl ether to carry out chloromethylation reaction after placing polymer pellets in water and dipping and dissolving lactose skeleton, obtaining the chlorinated pellets that the chlorine content is 18wt%;
[0050] a4) Dip the c...
Embodiment 3
[0052] Preparation of anion exchange resin:
[0053] a1) be that the lactose powder that the average particle diameter is 1.5mm is placed in methyl acrylate and carry out immersion adsorption 5min, filter out the lactose powder after its immersion absorption saturation;
[0054] a2) adding divinylbenzene to benzene methane to prepare a 10wt% reaction solution, adding cumene hydrogen peroxide to the reaction solution, the concentration of cumene hydrogen peroxide in the reaction solution is 0.05wt%, and every 100mL reacts 3 g of lactose powder adsorbed with methyl acrylate was added to the liquid, and placed under stirring conditions to react, and filtered to obtain polymer pellets with a cross-linking degree of 4.5%;
[0055] a3) polymer pellets are placed in water and dipped to dissolve the lactose skeleton and then add ferric chloride and chloroethyl ether to carry out chloromethylation reaction, to obtain the chlorinated pellets that the chlorine content is 15wt%;
