Removal of Congo Red Dye by Using Chemically Activated Lemon Peel Adsorbent

The synthetic colorant Congo red (CR) dye is an organic pollutant due to its resistance to decolorization. It is used in rubber, textiles, printing, and dyeing industries. Different dye-contaminated water can have adverse effects, including carcinogenicity and toxicity to biotic components. The discovery of CR dye, its noteworthy effects on aquatic life, and the ability of chemically activated lemon peel (LP) to function as an adsorbent were all made possible by this effort. The optimal conditions of dye concentration, adsorbent quantities, temperature, and contact period were assessed. The separation and removal of pollutants from wastewater were assessed by centrifuging the samples for the adsorption procedure, which is often used by spectrophotometers to evaluate LP’s capacity to remove CR. LP was…
