Synthesis of biodegradable and highly porous conductive hydrogel based on carboxymethyl cellulose and aniline; evaluation of dye removal capability

Today waste water treatment is an attractive challenge that encourages researchers to introduce new material with good performance. Among the developed materials,sorbent materials have more abundance because of easy synthesis, removal property with high efficiency and effortless recovery. In fact, sorption is one of the most frequently applied methods to remove pesticides, dissolved organic pollutants and other hazardous chemicals from waste water. Hydrogels are polymer networks possessing the ability to absorb water-based fluids, swelling to form a hydrated network [1]. Moreover, Modifications of hydrogels with conducting polymers (CPs) lead to multifunctional electrically conductive materials that retain the beneficial absorption properties of hydrogels [2]. In recent years, the emphasis of science and technology is shifting more towards environmentally friendly and sustainable resources and processes; in this regard biopolymers are attractive candidates to explore for supported materials [3]. So, in the present work, it has been tried to introduce a biodegradable conductive hydrogel with high porosity by radical polymerization of aniline in the presence of CMC and radical initiator. Batch process in the pollutant removal showed that the novel conductive hydrogel has high tendency for removal of high risk dyes such as methylene blue and rhodamine from aqueous media
