| titleOfInvention | A kind of heavy metal absorbent and its preparation method and application |
| abstract | The invention discloses a kind of heavy metal absorbent and its preparation method and application, the adsorbent is made up of the following raw material according to weight portion：27 35 parts of clay, 13 21 parts of dichloroacetic acid, 26 parts of isopropyl titanate, 5 12 parts of salicylic acid.By clay and isopropyl titanate mixed grinding, add di-chloroacetic acid solution ultrasonically treated, salicylic acid heated sealed stir process, then microwave treatment is added dropwise, to doing, high-temperature calcination is obtained final product for stirring.Obtained adsorbent of the invention, the adsorption efficiency of heavy metal is high, and reusable more than 100 times.The adsorption capacity of heavy metal absorbent of the present invention is high, and adsorption rate is fast；Preparation method is simple, the use of rear acid treatment is recyclable heavy metal, then 450 DEG C of high-temperature calcinations are renewable, are repeated high using number of times；Desorption is complete, heavy metal recovery low cost；Treatment heavy metal wastewater thereby has processing cost low, and process is simple, in the absence of secondary pollution, is suitable to industrialized production. |
