The objective of this research is to utilize a new poly[N,N-diallyl pyrrolidinium bromide-co-N,N-dimethyl acrylamide-co-acrylic acid sodium salt] superabsorbent hydrogel (SAH) for the removal of two anionic dyes, e.g., Reactive Red 5B (RR5B) and Reactive Orange M2R (ROM2R), from water. The SAH was characterized by swelling in water, FTIR, TGA and SEM. The SAH DDA(6) showed good swelling property and thermal stability. We have also investigated the parameters affecting dye adsorption such as pH, adsorbent dose, adsorption rate and initial dye concentration. The experimental data were also analyzed by applying the well known Langmuir and Freundlich isotherm models. (C) 2013 Manish P. Patel.
