| titleOfInvention | Bifunctional modified corn straw cellulose adsorbent, control synthesis method and application |
| abstract | The invention relates to the technical field of resource utilization and environmental protection of agricultural wastes, and particularly discloses a bifunctional modified corn straw cellulose adsorbent containing a primary/secondary amino group and a sulfur-containing group, a control synthesis method and application. The key point of the invention is to introduce a proper amount of CS on primary amino group on the surface of cellulose by an effective control synthesis method on the existing amino modified corn straw cellulose 2 Form a Dithiocarbamate (DTC) structure, thereby ensuring that the modified corn stalk cellulose contains Pb 2+ Having strongly chelating sulfur-containing groups and containing sufficient primary/secondary amino groups for Cu 2+ Trapping and adsorbing to realize the high-efficiency removal of mixed lead and copper ions in the wastewater, and mixing Cu under proper operating conditions 2+ And Pb 2+ The removal rate of the catalyst can quickly reach more than 99.6 percent and the catalyst can be regenerated and recycled. The invention has the characteristics of cheap and easily available raw materials, degradability, low toxicity, environmental protection and the like, widens the application field of the corn straws, and is beneficial to realizing the high-efficiency resource utilization of agricultural wastes. |
