| titleOfInvention | Ni2+the preparation of adsorbent and adsorption method thereof |
| abstract | The invention discloses Ni 2+ The preparation of adsorbent and adsorption method thereof, comprise the steps of (1) with tetraethyl orthosilicate for silicon source, triblock copolymer (P123, EO 20 PO 70 EO 20 ) it is template, synthesis of silica-base mesoporous material SBA 15, then by alkyl coupling method, 3 aminopropyltriethoxywerene werene (APTES) are modified to the inner surface of silicon-based mesoporous material SBA 15, obtain the silicon-based mesoporous material NH of amino functional 2 ‑SBA‑15；(2) after using, aminoacid is grafted onto NH by grafting 2 On SBA 15, obtain amino-acid modified after silicon-based mesoporous material, i.e. adsorbent；(3) containing Ni 2+ Aqueous solution, regulation pH value, to 3 ~ 5, puts into Ni in adsorbent water body 2+ , adsorbent and Ni in water body 2+ Mass ratio 5:1 ~ 8:1, adsorption temp 20 ~ 30 DEG C, adsorption time 10 ~ 30 min.The sorbent preparation method of the present invention is workable, favorable reproducibility, and the amino-acid modified silicon-based mesoporous material of gained is to heavy metal ion Ni in water body 2+ Having good removal effect, equilibrium adsorption capacity reaches 60 mg g ‑1 Above, actual application value is good. |
