| titleOfInvention | A kind of solid-phase extraction agent based on scraps of biological fiber facial mask and preparation method thereof |
| abstract | The invention discloses a solid-phase extraction agent based on biofiber facial mask scraps and a preparation method thereof. The preparation process is as follows: 1. After soaking the biofiber facial mask scraps in acid solution and alkali solution in sequence, wash them with ultrapure water until the lotion is neutral and dry; 2. Immerse the product obtained in step 1 in periodate solution, add hydroxyapatite catalyst, and after the reaction is completed, wash it with ultrapure water for many times; 3. immerse the product obtained in step 2 into The product is immersed in a mixed solution containing chitosan oligosaccharide, polyethylene polyamine and ciba blue 3GA, a reaction accelerator is added, and then washed with ultrapure water for several times to obtain the required solid phase extractant. The solid phase extractant prepared by the invention has extremely excellent treatment effect of heavy metal ion wastewater, can completely remove heavy metal ions in water within half an hour, and can be regenerated and reused. In addition, the ultra-high-efficiency solid-phase extractant of the present invention has the advantages of low price, simple preparation process, mild preparation conditions, and can be regenerated and recycled. |
