Embodiment 1
[0050] The preparation method of non-metallic water-soluble dissolved adsorbent comprises the steps:
[0051](1) Weigh 6 g (0.048 mol) of melamine, 0.8 g (0.02 mol) of sodium hydroxide, and 2.24 g (0.04 mol) of potassium hydroxide, and grind them thoroughly in a mortar to obtain a mixture.
[0052] (2) Add the mixture obtained in (1) into a covered crucible, put it into a muffle furnace and raise it from room temperature to 330 °C at a rate of 5 °C / min and keep it for 2 hours. After cooling to room temperature, it is fully ground into powder.
[0053] (3) Dissolve the powder obtained in (2) in 400ml ultrapure water, and then put it into a 3500Da dialysis bag for dialysis for 4 days to obtain a non-metallic water-soluble adsorbent based on the reversible phase transition function.
Embodiment 2
[0055] The difference between the present application and Example 1 is that the raw material consumption of the present example is different from Example 1, and the difference is as follows: 6g (0.048mol) melamine and 0.8g (0.02mol) sodium hydroxide are fully ground in a mortar, Obtain the mixture, then take the calcination and dialysis process of Example 1 to obtain the non-metallic water-soluble adsorbent.
Embodiment 3
[0057] The difference between the present application and Example 1 is that the raw material consumption of the present example is different from Example 1, and the difference is as follows: 6g (0.048mol) melamine and 2.44g (0.04mol) potassium hydroxide are fully ground in a mortar, Obtain the mixture, then take the calcination and dialysis process of Example 1 to obtain the non-metallic water-soluble adsorbent.
