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 114.4 mg.g-1. 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 91.40%. therefore, the hydrogel appears great potential for the wastewater.
