Powdered of Highly Porous Hydrogel Nanocomposite Prepared from Acrylamide- Acrylic Acid -Treated by Activated Carbon for Brilliant Blue Dye Removal

With the ex-potentially increase pollutants of dyes, the purification of cationic dye waste water has been an urgent environmental problem. As a new kind of porous adsorbent, hydrogel modified activated carbon frameworks still face challenges in agglomeration, regeneration, reuse ability, and synthesis environmentally un-friendly. In this work, activated carbon was grown in situ on the surface of sodium alginate (AAc-AM) beads to fabricate (AAc-co-AM)/AC. This study works to examine the elimination of Brilliant Blue (BB), a harmful and persistent dye that could cause extensive ecological damage, from an aqueous solution via adjusting the amount of acrylamide (AM) and the degree of co-polymer cross-linking. The co-polymer of hydrogels efficiently removes BB in a brief time frame. The synthesized hydrogel was characterized via FESEM and TEM. The best adsorption efficiency of the nanocomposite was ۱۱۴.۴ mg.g-۱. Reactivation appears to indicate that the material could be utilized repeatedly and has a better ability to resist interference. In addition, the percentage removal of BB dye by hydrogel from aqueous solution were above ۹۱.۴۰%. Therefore, the hydrogel appears great potential for the wastewater.
