| titleOfInvention | Method for preparing nano composite gel for removing divalent cadmium in wastewater |
| abstract | The invention discloses a method for preparing nano composite gel for removing divalent cadmium in wastewater, which comprises the following steps: taking hydroxyethyl chitosan and clinoptilolite as raw materials, grafting acrylamide to hydroxyethyl chitosan macromolecules through a free radical graft copolymerization reaction, mixing the hydroxyethyl chitosan macromolecules and the clinoptilolite, cleaning and drying a resultant, and performing ball milling to obtain the nano-scale clinoptilolite/hydroxyethyl chitosan graft copolymer composite gel; the nano composite gel adsorbent obtained by the method is in a grey white powder shape, can efficiently remove divalent cadmium ions in wastewater, has no pollution to the environment, is green and environment-friendly, and not only can improve the comprehensive utilization efficiency of natural macromolecules such as chitosan derivatives and clinoptilolite, but also can improve the comprehensive utilization efficiency of Cd in heavy metal wastewater 2+ The efficient adsorption and removal provides a feasible scheme, and the application prospect is wide. |
