Utilization of "red mud" being a part of new effective adsorbent in water treatment

Abstract

Storage of red mud, because of its large quantity and specific compounds, causes a lot of problems. Thereby, development of complex technology utilization of wastes (red mud) is the most economically and environmentally attractive way to solve the problem of red mud accumulation and obtaining of highly efficient purification reagents from secondary raw materials. The purpose of this work is synthesis and verification of efficacy of adsorption reagents that were obtained by using "red mud" in technologies of wastewater treatment from compounds of organic origin. The proposed sorption reagent derived from activated "red mud" and activated carbon brand F300 revealed sufficient sorption efficiency at wastewater treatment from the dye "Active brilliant blue KX". At the the initial concentration of dye 10, 30, 50 mg/l dye extraction to 84–100% in following conditions was achieved: рН medium 4 – 4,3, dose of sorbent 12 g/l, asdorption duration 150 min. Conducted research revealed that synthesized sorbent based on activated "red mud" and activated carbon (where activated carbon functionates as carrier) has potential for use in water treatment to remove organic dyes.
