Embodiment 1
[0085] A preparation method of phenone anti-bioadhesion uranium extraction material, the following steps are carried out in sequence:
[0086] (1) Synthesis of styrene-divinylbenzene copolymer crosslinked microspheres
[0087] Preparation of monomer phase: add 31.3g styrene and 9.5g divinylbenzene (50% content) into a 200mL beaker, then add 0.42g BPO and 80g isooctane, stir and mix well.
[0088] Preparation of the dispersed phase: Add 300mL of deionized water into a 1L three-neck bottle, then add 3g of gelatin, start stirring and heat to dissolve the gelatin.
[0089] In the state of heating and stirring, the monomer phase was slowly added to the dispersed phase; the reaction was stirred at 90°C for 12 hours; after the reaction, the copolymer crosslinked microspheres were separated from the solution by suction filtration, and washing the microspheres with water; adding the washed microspheres to boiling water for 2 hours to remove residual organic matter, filtering and dryin...
Embodiment 2
[0107] A preparation method of a phenolic functional group anti-bioadhesion uranium extraction material, the following steps are performed in sequence:
[0108] (1) Synthesis of styrene-divinylbenzene copolymer crosslinked microspheres
[0109] Preparation of monomer phase: add 31.3g styrene and 12.5g divinylbenzene (50% content) into a 200mL beaker, then add 0.45g BPO and 90g isooctane, stir and mix evenly;
[0110] Preparation of dispersed phase: Add 300mL deionized water to a 1L three-necked bottle, then add 3g of gelatin, start stirring and heat to dissolve the gelatin;
[0111] In the state of heating and stirring, slowly add the monomer phase into the dispersed phase; and solidify at 100° C. for 24 hours. After the reaction is over, the copolymer crosslinked microspheres are separated from the solution by suction filtration, and the microspheres are washed with water; the washed microspheres are added to boiling water and boiled for 1.5 h to remove the pore-forming agen...

[0121] A preparation method of a phenolic functional group anti-bioadhesion uranium extraction material, the following steps are performed in sequence:
[0122] (1) Synthesis of styrene-divinylbenzene copolymer crosslinked microspheres
[0123] Preparation of monomer phase: add 31.3g styrene and 11g divinylbenzene (50% content) into a 200mL beaker, then add 0.42g BPO and 80g isooctane, stir and mix evenly;
[0124] Preparation of dispersed phase: Add 300mL deionized water to a 1L three-necked bottle, then add 3g of gelatin, start stirring and heat to dissolve the gelatin;
[0125] Slowly add the monomer phase into the dispersed phase while heating and stirring; and solidify at 85° C. for 12 hours. After the reaction, the copolymer cross-linked microspheres were separated from the solution by suction filtration, and the microspheres were washed with water; the washed microspheres were added to boiling water and boiled for 1 hour to remove residual organic matter, separated fro...
