ABSTRACT Wastewater treatment contributes to the sustainable utilization of water resources for alleviating scarcity. The application polymeric materials as adsorbents eliminating hazardous substances in has garnered extensive attention owing their remarkable adsorption efficiency, stability, and selectivity. Herein, a facile strategy is provided rapidly synthesize poly(acrylic acid‐ co ‐sodium 2‐acrylamide‐2‐methylpropanesulfonate) (poly(AA‐ ‐NaAMPS)) hydrogels with exceptional adsorptive capacity via frontal polymerization (FP). FP processes are meticulously examined terms initiator dosage monomer ratio. as‐prepared demonstrate pH‐responsive swelling ability pH‐dependent various dyes heavy metal ions. Compared traditional batch (BP), prepared by exhibit superior abilities. Additionally, research on mechanism both ions conducted fitting kinetic data Langmuir Freundlich equations. maximum ( q m ) derived from model methylene blue (MB) rhodamine B (RB) is, respectively, 595.3 3078.5 mg g −1 , while Cr 3+ Cd 2+ 1010.8 1191.3 . This exploits an alternative approach rapid preparation high‐efficiency hydrogel toward wastewater treatment.
