Herein, gum ghatti (GGTI)--[sodium acrylate (SA)--3-(-(4-(4-methyl pentanoate))acrylamido)propanoate (NMPAP)--4-(acrylamido)-4-methyl pentanoate (AMP)---isopropylacrylamide (NIPA)] (i.e., GGTI--TetraP), a novel interpenetrating tetrapolymer network-based sustainable hydrogel, possessing extraordinary physicochemical properties and excellent recyclability, has been synthesized via grafting of GGTI and in situ strategic protrusion of NMPAP and AMP during the solution polymerization of SA and NIPA, through systematic multistage optimization of ingredients and temperature, for ligand-selective superadsorption of hazardous metal ions (M(II)), such as Sr(II), Hg(II), and Cu(II).
