Examples
preparation example 1
[0047] In this preparation example, the adsorbent is prepared according to the following method:
[0048] (1) 40kg natural zeolite powder, 40kg glycerol, 160kg lithium hydroxide solution are mixed uniformly to obtain mixed solution 1; in this step, the pH of mixed solution 1 is 10;
[0049] (2) Add 8kg of hydroxymethyltriethoxysilane and 8kg of vinyltriethoxysilane to the mixed solution 1, stir evenly and heat to 60°C to obtain the mixed solution 2;
[0050] (3) Remove the liquid component in the mixed liquid 2, grind the remaining solid component, and then screen the powder with a particle size between 350-550 μm to obtain the adsorbent.
[0051] As shown in Table 1, the difference between Preparation Examples 1-5 is that the ratio of raw materials is different.
