Removal of Color from Different Dye Wastewater by Using Ferric Oxide as an Adsorbent (original) (raw)

Dyes are colored organic compounds that are used to impart colour to various substrates including paper, leather, fur, hair, drugs, cosmetics, waxes, greases, plastics and textile materials. The discharges of industrial wastewater containing dyes cause serious environmental problems. There are many colour removal techniques amongst which adsorption process is popular. Many removal techniques have been applied. But, adsorption process is inexpensive and readily available to control the various pollutants from the water and wastewater. The practical performance evaluation in batch reactor is carried out because of its feasibility and simplicity in action and also involving less economic aspects. Present work is carried out on colarane blue BGFS Anthraquinone dye. Powdered Fe 2 O 3 has been used for dye removal practical. It was observed that maximum dye removal efficiency at pH 2 with Fe 2 O 3 dosage of 0.3 gm and initial concentration is 125 ppm. Practicals were also carried out on actual wastewater. The work is right now done with the synthetic dye wastewater and will be focused with different parameters. The percentage removal efficiency by powdered Fe 2 O 3, the dye waste water under experiment will be calculated. Kinetic study and adsorption study for dye wastewater under consideration.
