“…(16) as described in the literature [26] where q e (mmol/g) and q t (mmol/g) are the amounts of CP + adsorbed at equilibrium and at time t, respectively, k 1 (min -1 ) and k 2 (g/mmol min) are rate constants of the first order and the second order, respectively. log (q e -q t ) = log q e -k 1 t / 2.303 (15) t / q t = 1 / k 2 q e 2 + t / q e (16) The experimental study of the adsorption kinetics of CP + on (AlPO 4 ) C (Fig. 9a1) showed a fast adsorption in the first minutes and reached a steady state, particularly at concentrations below the Critical Micelle Concentration (CMC).…”

“…In comparison with the recent studies, the e ect of space velocity is low in this study. This could be due to the three-dimensional and bimodal pore structure of SBA-3, which leads to less constrained di usion of guest molecules into the pores in comparison with the twodimensional unimodal pore system of other mesoporous materials such as MCM-41 [42][43][44]. When there is low di usion limitation, the e ect of temperature becomes predominant, even with respect to ZnO content.…”

One of the appropriate methods for the preparation of such sorbent is embedding of proper metal oxides such as ZnO (active part) on silicate mesoporous materials [43][44][45][46].…”

Abstract. H 2 S is a major toxic compound that could be found in air, water, and fossil fuels and causes some bad e ects such as acidic rain and corrosion. In the present work, SBA-3 (Santa Barbara University no. 3) with three di erent weight percentages of ZnO, namely, 5%, 10%, and 15%, was synthesized via an in situ approach. All synthesized samples were characterized using atomic absorption spectrometry, X-Ray Di raction (XRD), nitrogen adsorption, and Transmission Electron Microscopy (TEM). The obtained results from XRD and nitrogen adsorption con rmed that all the samples almost retained their ordered structure after incorporation of ZnO nanoparticles within the mesopores of SBA-3. TEM images showed that ZnO nanoparticles were arranged along the direction of mesopores of SBA-3. Then, adsorption of H2S from a model gas was investigated. A three-factor Box-Behnken design with ve center points and one response was performed for the evaluation of e ect of three process parameters, namely, ZnO wt%, space velocity, and temperature, on the adsorption of H 2 S and a quadratic model (r 2 : 0.9185) was developed to navigate the design space. Temperature had the largest and space velocity had the lowest e ect on the breakthrough of H 2 S. The optimum breakthrough time (t bp ) was 588 min.

“…Adsorption of some cationic and anionic surfactants from aqueous solutions on the commercial activated carbon cloth Spectracarb 2225 (Spectra Corp., USA) was examined [140,141]. A specially designed V-shaped cell was employed in these studies to perform adsorption assays and simultaneous in situ concentration measurements by in situ UV absorption spectrophotometry.…”

Activated carbon cloths have received growing attention because they offer comparative advantages over the traditional powdered or granular forms of this well-known adsorbent, providing further potential uses for technological innovations in several fields. The present article provides an overview of research studies and advances concerned with the development of activated carbon cloths and their use as adsorbent in environmental applications, mostly reported in the last years. The influence of some fabrics and textile wastes used as precursors, and of main activation process variables on the development and physicochemical, mechanical and/or electrical properties of the resulting activated carbon cloths are first reviewed. Then, investigations dealing with the removal of water and air pollutants by adsorption onto activated carbon cloths, including advances toward optimizing their regeneration after organic vapors saturation, are presented.
