Abstract
The task of removing cationic dyes from industrial effluents remains a crucial one in the field of environmental remediation, despite its difficulty. Each year, thousands of tons of coal are mined. The cationic dyes and plastics industries, which produce between 10 and 20 percent of the water effluents, largely consumed by the textile, rubber, paper, and other materials industries. The most popular dye for cotton, wood, and silk is methylene blue (MB), but using it might result in eye burns that could permanently harm both human and animal eyes. Since most dyes are resistant to photo- and biodegradation The removal of MB from waste effluents is becoming more and more important for the environment. Because of this, colored wastewater is a hazard to conventional wastewater treatment techniques. Approaches to treating wastewater, many methods have been employed in the past, like as Examples of coagulation and flocculation include membrane separation, oxidation, and coagulation. Other processes include adsorption, ozonation, and electro coagulation. Adsorption has been identified as a successful, affordable, and potentially helpful method for removing dyes or other infectious agents. A variety of adsorbents have also been developed and are being utilized to successfully remove color from a range of surfaces. Adsorbents of many different kinds were created and utilized to successfully remove color from aqueous effluent. 2 Natural polymeric materials have received a lot of attention recently since they are renewable, biodegradable, non-toxic, and have the potential to be an environmentally benign material. The second-most common natural biopolymer is chitosan (CS), an Ndeacetylated derivative of chitin. CS is a well-known sorbent that is frequently used to remove heavy metals and colors. Since CS is a naturally occurring cationic polysaccharide, it can only absorb a very minimal amount of cationic dyes. Additionally, its practical application was constrained by its low specific gravity and somewhat high market cost. Recently, clays such as montmorillonite.
