One of the most dangerous pollutants found in many industries, including plastic, paper, food, cosmetics, leather, textiles, and pharmaceuticals, is synthetic dye.[1] Even at low concentrations, many of these dyes are harmful to humans and animals because they are carcinogenic and toxic. There has been a lot of work done to get the pollutants out of the industrial wastewater because synthetic dye use is linked to environmental issues.[2,3] Absorption is one of the most popular and intriguing methods for removing dyes from aqueous environments among the various techniques for removing dyes from wastewater.[4,5] In order to remove some dyes such as Methylene Blue (MB) and Malachite Green (MG) from aqueous solutions, this study looks into how effective hydrogels are as adsorbents. This study produced a novel hydrogel by radical polymerizing and crosslinking acrylic acid (AA) in the presence of sodium alginate (Na-Alg). In this research, a hydrogel was produced utilizing acrylic acid polymerization, and after various techniques of characterization such as FT-IR, TGA, XRD, and SEM its potential as an absorbent for eliminating Methylene Blue (MB) and Malachite Green (MG) dyes was examined. To achieve the best dye elimination condition, several parameters such as the pH of the dye solution, dye concentration, absorbent dose, and contact time, were examined. These findings demonstrate the synthesized hydrogel promising potential as efficient adsorbents for dye removal.
