Abstract

A complex Remazol dye effluent, comprised of four reactive dyes and auxiliary chemicals, was decolorized using SPS-200 (sawdust-based) and SPC-100 (coal-based) activated carbons. A detailed characterization revealed that the pore diameter of the activated carbon played an important role in dye adsorption. The solution pH had no significant effect on the adsorption capacity in the pH range of 2-10.7. According to the Langmuir model, the maximum uptakes of SPS-200 were 415.4, 510.3, 368.5 and 453.0 mg g(-1) for Reactive Black 5 (RB5), Reactive Orange 16 (RO16), Remazol Brilliant Blue R (RBBR) and Remazol Brilliant Violet 5R (RBV), respectively. Conversely, those of SPC-100 were slightly lower, at 150.8, 197.4, 178.3 and 201.1 mg g(-1) for RB5, RO16, RBBR and RBV, respectively. In the case of Remazol effluent, SPS-200 exhibited a decolorization efficiency of 100% under unadjusted pH conditions at 10.7, compared to that of 52% for SPC-100.
