摘要：NOVELTY - Mesoporous chelating resin preparation involves adding 1-5 g organic cross-linking agent, 1-5 g unsaturated compound containing phosphorus and oxygen functional groups and 0.02-0.08 g azobisisobutyronitrile in 1-10 ml organic solvent at 25 degrees C under stirring for 1-3 hours. The resulting solution is added in a hydrothermal reaction vessel at 100 degrees C for 24 hours, and then placed in open kettle for evaporating organic solvent. The resulting mixture is dried under vacuum at 45 degrees C for 12-24 hours to obtain the mesoporous chelating resin. USE - Method for preparing mesoporous chelating resin for separating uranium and polymeric adsorbent (all claimed). ADVANTAGE - The method prepares the mesoporous chelating resin in a simple, cost-effective and eco-friendly manner with high adsorption capacity and high adsorption speed.
