| titleOfInvention | Clay heavy metal adsorbent, and preparation method and application thereof |
| abstract | The invention discloses a clay heavy metal adsorbent, and a preparation method and application thereof. The adsorbent comprises the following raw materials in parts by weight: 27-35 parts of clay, 13-21 parts of ethyl acetate, 2-6 parts of titanium isopropylate and 5-12 parts of saligenol. The preparation method comprises the following steps: performing mixed grinding on the clay and the titanium isopropylate; adding the ethyl acetate solution, and performing ultrasonic treatment; and dropwisely adding the saligenol, stirring while heating in a sealed manner, then performing microwave treatment, stirring to dryness, and performing high-temperature calcination. The adsorbent prepared by the invention has very high heavy metal adsorption efficiency, and can be repeatedly used for more than 100 times. According to the invention, the clay heavy metal adsorbent has high adsorption capacity and high adsorption rate; the preparation method is simple; after use, heavy metal can be recovered by performing acid treatment, the adsorbent can be regenerated by performing high-temperature calcination at 450 DEG C, and the adsorbent can be repeatedly used for many times; the desorption is complete, and the recovery cost of the heavy metal is low; and the heavy metal treatment wastewater has the advantages of low treatment cost, simple process and no secondary pollution, thereby being suitable for industrial production. |
