Removal of Selected Dyes on Activated Carbons

Dyes are widely used in various industries such as those involving paper, food, plastics, and fibers. The produced wastewater has a specific character. Organic substances found when introduced into natural water bodies have toxic effect on living organisms, causing increased chemical biological oxygen demand. Some dyes, even very low concentrations, cause intense colouring. To remove dyes from wastewater, methods flotation, oxidation, ozonation, filtration or coagulation with metal compounds used. Unfortunately, these used, large amounts of sludge produced, which is another problem for the environment. Therefore, one that can effectively without creating waste activated carbon adsorption. Adsorption treatment dye industry particular importance due to their high efficiency, ability operate over relatively wide range availability. most common adsorbent carbon, adsorption capacity against many organic compounds. aim this study was determine rate type removal efficiency selected cationic (anilan yellow) anionic (tartrazine) aqueous solutions.
