Data on the alizarin red S adsorption from aqueous solutions on PAC, treated PAC, and PAC/gamma approximate to Fe2O3

Three types of adsorbents of powdered activated carbon (PAC), treated PAC, and PAC/gamma approximate to Fe2O3 nanocomposite were used. The adsorption experiments were performed in batch conditions. pH(ZPC) of PAC/gamma approximate to Fe2O3 was 6.7. As a result, at lower than pH(ZPC), acidic pH, the adsorption of alizarin red S on PAC/gamma approximate to Fe2O3 was favourable. The maximum of alizarin red S adsorption of PAC, treated PAC, and PAC/gamma approximate to Fe2O3 was 24.5 mg/g, 57.8 mg/g, and 112.56 mg/g, respectively. The models of Langmuir and pseudo first-order were a fit model to describe the adsorption isotherm and the Kinetic, respectively. The PAC/gamma approximate to Fe2O3 is a promising class of the adsorbents in the adsorption of various dyes from textile effluents. (C) 2018 The Authors. Published by Elsevier Inc.
