Data on the alizarin red S adsorption from aqueous solutions on PAC, treated PAC, and PAC/γ≈Fe2O3

Abstract

Three types of adsorbents of powdered activated carbon (PAC), treated PAC, and PAC/γ ≈ Fe2O3 nanocomposite were used. The adsorption experiments were performed in batch conditions. pHZPC of PAC/γ ≈ Fe2O3 was 6.7. As a result, at lower than pHZPC, acidic pH, the adsorption of alizarin red S on PAC/γ ≈ Fe2O3 was favourable. The maximum of alizarin red S adsorption of PAC, treated PAC, and PAC/γ ≈ 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/γ ≈ Fe2O3 is a promising class of the adsorbents in the adsorption of various dyes from textile effluents.

Degradation of methylene blue in aqueous phase by homogenous and heterogeneous catalytic Ozonation

“…There are many different types of oxidation processes, each with its advantages and disadvantages. Single Ozonation Processes (SOP s ) is one of these processes which has been used in some studies (Kamarehie et al, 2018a;Kamarehie et al, 2018b;Schumacher et al, 2011). These processes, SOP s , have relatively low e ciency in removing contaminants and do not completely oxidize the contaminants (Asgari et al, 2015;Kamarehie et al, 2018a).…”

“…One of the most common compounds that can be used is activated carbon (GAC and PAC). Recently, the authors of this paper have reported that nanocomposite of MgO/PAC and PAC/γ-Fe 2 O 3 have high destructive adsorption, and high catalytic potential in the degradation of different pollutants including bisphenol A and Alizarene Red S (ARS) (Desalination-phenol;Kamarehie et al, 2018a;Kamarehie et al, 2018b;Kamarehie et al, 2018c). The environment is exposed to various pollutants daily, and the amount of pollution is increasing, day by day.…”
