High-selectivity heavy metal ion adsorbent as well as preparation method and application thereof
A heavy metal ion, high-selectivity technology, applied in the directions of alkali metal compounds, chemical instruments and methods, adsorbed water/sewage treatment, etc., can solve the problems of difficult separation, treatment or recovery of adsorbed metal ions, and reduce the cost of loading times and raw materials. The effect of its own price cost, good adsorption performance and selectivity, and good identification

Embodiment 1
[0041] A kind of highly selective heavy metal ion adsorbent, its preparation method is as follows:
[0042] I. Formation of Cu-ABN-VI complexes
[0043] Dissolve 10 mmol of 2-aminobenzonitrile in 100 mL of ethanol, stir at room temperature at high speed to make the reaction fully, and then add Cu 2+ The solution was continuously stirred until a precipitate was obtained, and the precipitate was filtered and washed with methanol and acetone for 3 times in turn, and then vacuum-dried for 24 h to obtain the Cu-ABN complex, which was used for later use;
[0044] At room temperature, 5 mmol of Cu-ABN complex and 1-vinylimidazole were dispersed in 100 mL of cyclohexane, stirred for 3 h, the product was successively washed three times with methanol and acetone successively to obtain Cu-ABN-VI, and then vacuum dried 24h, standby;
[0045] II. Highly selective Cu 2+ Preparation of adsorbents
[0046] 2.5 mmol of Cu-ABN-VI, 25 mmol of divinylbenzene, 25 mmol of styrene, 0.12 g of azo...
