Adsorption of Anionic and Cationic Dyes from Textile Effluents by Activated Carbon Prepared from Sawdust and Fish Scale

In Bangladesh, there are thousands of textile-dying industries spread across the country’s many regions, majority which involve knitting and dying. The dyeing industry uses an enormous quantity water, as well colors chemicals. After dying process has been completed, they also release a significant amount wastewater. Cotton, wool, polyester fiber typically dyed with textile dyes such reactive, acid, disperse dyes. These utilized most frequently in respective sectors. dyes’ colorants extremely poisonous dangerous to all forms life, including aquatic life living things. present work intended investigate whether or not it is practicable remove commonly used simultaneously from aqueous dye solution using adsorption technique that makes use variety different adsorbents. This study focuses on removal color two distinct types dyes—Methylene Blue Reactive Blue-250 cationic anionic nature respectively, activated carbon adsorbents prepared sawdust fish scale. Dye capacity was tested function contact time, dosage adsorbent, pH during treatment process, temperature initial concentration dye. applicability Langmuir Freundlich isotherms describing experimental data investigated. micro mesoporous scale identified by Scanning Electron Microscopy (SEM) images indicated large surface area have more potential whereas variation occurs due area. From overall data, maximum 95.39% 87.92% found for Methylene respectively sawdust, 90.64%
