Embodiment 1
[0043] Taking 10g of resin white balls as an example, use 25mL of amino interpenetrating resin adsorbent beads (basic structure such as figure 1 shown)
[0044] The preparation method is as follows:
[0045] Dissolve 2g of gelatin, 1.05g of trisodium phosphate, 4.2g of disodium hydrogen phosphate and 32.5g of sodium chloride in 250mL of deionized water, heat to 55°C to dissolve it completely, then add 12.5g of divinylbenzene, 12.5g Glycidyl methacrylate, 0.5g benzoyl peroxide, 0.5g azobisisobutyronitrile and 62.5g oil phase of toluene, heated to 70°C to start the reaction, reacted at 75°C for 2h, heated to 80°C to react 2h, and then heated to 90°C for 10h to complete the reaction to obtain white resin balls, which were washed with deionized water and acetone at 65°C to remove impurities.
[0046] Take 10 g of cleaned resin white balls and add them to the reaction device, use 100 mL of ethanol to swell for 1 hour, then extract excess ethanol, add 25 mL of dimethylamine soluti...
Embodiment 2
[0051] Taking 20g of resin white balls as an example, use 75mL of amino interpenetrating resin adsorbent beads modified with a dimethylamine solution with a concentration of 5mol / L
[0052] The preparation method is as follows:
[0053] Take 2.5g of gelatin, 1.05g of trisodium phosphate, 4.2g of disodium hydrogen phosphate and 32.5g of sodium chloride and dissolve them in 250mL of deionized water, heat to 53°C to dissolve them completely, then add 12.5g of divinylbenzene, 12.5 g glycidyl methacrylate, 0.5g benzoyl peroxide, 0.5g azobisisobutyronitrile and 45g oil phase of toluene, heated to 70°C to start the reaction, reacted at 75°C for 1.5h, heated to 80°C React for 1.5 hours, then heat to 95° C. and react for 11 hours to obtain white resin balls. Use 75° C. deionized water and ethanol to wash away impurities.
