Study on the adsorption capacity Congo Red of nanocomposite xCoFe2O4 /(1-x)TiO2-5%La

Abstract

In this paper, nanocomposite materials of xCoFe2O4/(1-x)(TiO2–5%La) (x = 0.2) were synthesized in a two-step procedure, combining a co-precipitation and hydrothermal methods. The morphological and structural characteristics of the material were studied through XRD, SEM, EDS, BET measurements. The materials showed the high adsorption capacity for a organic dye - Congo Red (CGR) . The adsorption efficiency reaches 99.34% after 10 minutes of treatment process, with the amount of adsorbent used is 0.04g /100ml of solution of 32 µmol/l CGR.
