| description | The invention discloses a selenium functionalized porous material and a preparation method and application thereof, a selenium ether silane coupling agent is used for graft modification of a porous material in the presence of a solvent, and a selenium-containing loaded porous material is obtained. According to the invention, a novel silyl ether surface modifier is constructed, and the porous material is modified by a chemical grafting method, so that the selenium-functionalized porous material is obtained. The preparation method is simple to operate, low in cost and suitable for mass production of the selenium functionalized porous material; and the prepared selenium functionalized porous material shows high adsorption capacity, high adsorption rate, high selectivity and reducibility to gold ions, can be used for statically or dynamically adsorbing free gold elements in wastewater and reducing the gold ions in situ to obtain gold elementary substances, and has a good application prospect in the aspect of gold |
