AbstractActivated carbon (AC) was modified by using non-thermal plasma in O2, N2 and O2/N2 atmospheres to increase its Cu(II) adsorption capacity and quantify the influences of the modifying atmospheres. SEM, BET, FT-IR and XPS were used to characterize the surface physical and chemical properties of AC. The results show that the AC modified by using plasma had significantly better Cu(II) adsorption performance than the raw AC. Among the O2, N2 and O2/N2 atmospheres, the AC with plasma modification in N2 showed best Cu(II) adsorption performance and the Cu(II) adsorption capacity was 369.5% higher than the raw AC. The AC modified in O2 atmosphere can form C—COOH groups, while the AC modified in N2 atmosphere can form C—NH2 groups. These two groups are both beneficial for Cu(II) adsorption, where the —NH2 groups are more effective for Cu(II) adsorption compared to —COOH groups. The chemisorption dominated the Cu(II) adsorption on the plasma modified AC and the adsorption performance was dependent on the surface functional groups properties of AC.

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.
