Dicyandiamide-Modified Ultrahighly Cross-Linked Polystyrene Resin for Selective CL-20 Adsorption from Explosive Waste Acid
was achieved. Evaluation of the thermodynamic parameters revealed that the adsorption was spontaneous and endothermic. Meanwhile, ethyl acetate enabled highly efficient desorption, with efficiency reaching up to 100%. X-ray photoelectron spectroscopy (XPS) and molecular dynamics simulations demonstrated that the adsorption is primarily driven by hydrogen bonding and polar interactions. Based on these findings, the modified resin is posited as a promising material for the effective adsorption and recovery of CL-20 from waste acid.
