Embodiment 1
[0029] Macroporous adsorption resin, made from the following raw materials in parts by weight: 1000 parts of pure water, 5 parts of gelatin, 0.5 parts of methylene blue, 100 parts of methyl acrylate, 10 parts of triallyl isocyanurate, diethylene 8 parts of benzene, 50 parts of porogen, 1.5 parts of benzoyl peroxide. Wherein, the porogen is composed of cyclohexane and tetrabutylammonium-lysine in a weight ratio of 4:1, and tetrabutylammonium-lysine is made by the following steps:
[0030] Add tetrabutylammonium hydroxide into water and mix uniformly to obtain tetrabutylammonium hydroxide aqueous solution, add lysine in tetrabutylammonium hydroxide aqueous solution, the molar ratio of tetrabutylammonium hydroxide and lysine is 1 : 1.5, stirred and reacted at room temperature for 15 hours, then vacuum evaporated water at 60°C, dried in vacuum at 70°C for 24 hours to obtain a crude product, added the crude product to acetonitrile and stirred for 8 hours to obtain a mixed solution,...
Embodiment 2
[0038] Macroporous adsorption resin, made from the following raw materials in parts by weight: 950 parts of pure water, 6 parts of gelatin, 0.6 parts of methylene blue, 90 parts of methyl acrylate, 10.5 parts of triallyl isocyanurate, diethylene 7.5 parts of benzene, 45 parts of porogen, and 1 part of benzoyl peroxide. Wherein, the porogen consists of cyclohexane and tetrabutylammonium-lysine in a weight ratio of 4:1, and the preparation steps of tetrabutylammonium-lysine are the same as in Example 1.
[0039] The preparation method of this a kind of macroporous adsorption resin comprises the following steps:
[0040] S1. Heat the pure water to 50°C, add gelatin, stir for 40 minutes to dissolve the gelatin, then add methylene blue and continue stirring until the mixture is uniform to obtain the water phase;
[0041] S2. Mix methyl acrylate, triallyl isocyanurate, divinylbenzene, and benzoyl peroxide, add porogen after stirring for 16 minutes, and continue stirring for 14 minu...
Embodiment 3
[0046]Macroporous adsorption resin, made from the following raw materials in parts by weight: 1050 parts of pure water, 4 parts of gelatin, 0.5 parts of methylene blue, 95 parts of methyl acrylate, 11 parts of triallyl isocyanurate, diethylene 7 parts of benzene, 48 parts of porogen, and 2 parts of benzoyl peroxide. Wherein, the porogen consists of cyclohexane and tetrabutylammonium-lysine in a weight ratio of 4:1, and the preparation steps of tetrabutylammonium-lysine are the same as in Example 1.
[0047] The preparation method of this a kind of macroporous adsorption resin comprises the following steps:
[0048] S1. Heat the pure water to 55°C, add gelatin, stir for 20 minutes to dissolve the gelatin, then add methylene blue and continue stirring until the mixture is uniform to obtain the water phase;
[0049] S2. Mix methyl acrylate, triallyl isocyanurate, divinylbenzene, and benzoyl peroxide, add porogen after stirring for 10 minutes, and continue stirring for 20 minutes...
