| titleOfInvention | Chromic method in the preparation of amino modified attapulgite clay adsorbent and removal water |
| abstract | The preparation method of amino modified attapulgite clay adsorbent, carries out reaction by amino agents and silane coupler and obtains solution A；Utilize solution A that pretreated attapulgite's surface is carried out graft reaction, obtain.The invention also discloses and utilize amino modified attapulgite clay adsorbent to remove chromic method in water, the amino modified attapulgite clay adsorbent of its quality 0.0005 times is added in the water body to be purified, 25 DEG C, pH be to adsorb Cr VI in water under conditions of 3.0～9.9, amino modified attapulgite clay adsorbent, the Cr VI in purifying water body is collected after absorption 10min～24h.Attapulgite is modified by the present invention with amido reagent, and synthesis has the attapulgite clay adsorbent of high amino content；Modified attapulgite stable chemical nature, not affected by outside environmental elements, and the inventive method is simple to operate, with low cost, absorption property is good. |
