There is an urgent requirement to develop excellent dye adsorbent, which contains high dye removal capacity with desirable separation property which are imperative to remove anionic and azo dyes from aqueous solutions. To address this issue, novel polymer composites were synthesized with varying reaction parameters, owing to the fact that various grades of graft polymer composites have been optimized. As-synthesized bioadsorbent materials were examined in details by FT-IR, XRD, TGA, SEM-EDX, and VSM. The factors affecting the dye adsorption performance, including the effect of initial dye concentration, adsorbent dosage, treatment time, pH as well as recycling data, were systematically investigated. The reusability test shows that polymer composite can be renewed easily with HCl/NaOH solution as an efficient adsorbent for practical wastewater treatment. The conditions depending on adsorption equilibrium consistent with Langmuir isotherm model and pseudo-second-order kinetic model are the predominant models to describe the experimental data well. Henceforth, this work provided a unique strategy for the design of low-cost bioadsorbent, which can be utilized with grafting various monomers to get features pH-responsive polymer composites for removing targeted emerging dyes from aqueous solutions with rapid and high-adsorption efficiency.
