Adsorption of bisphenol a from aqueous solutions by activated tyre pyrolysis char – Effect of physical and chemical activation

This paper aims to show the eﬀect of activation method of tyre pyrolysis char (TPC) on adsorption of bisphenol A (BPA) from aqueous solutions. The TPC was produced from end-of-life-tyres (ELT) feedstock in a pilot plant at 773 K. Activation was accomplished using two classical methods: physical activation with CO 2 and chemical activation with KOH. The two produced adsorbents had pores ranging from micro-to macropores. Distinct diﬀerences in the BET surface areas and pore volumes between the adsorbents were displayed showing better performance of the chemically activated adsorbent for adsorption of BPA from water. The results of the kinetic studies showed that the adsorption of BPA followed pseudo-second-order kinetic model. The Freundlich, Langmuir, Langmuir–Freundlich and Redlich–Peterson isotherm equations were used for description of the adsorption data. The Langmuir–Freundlich isotherm model best ﬁts the experimental data for the BPA adsorption on both adsorbents. The Langmuir–Freundlich monolayer adsorption capacity, q mLF , obtained for the CO 2 -activated tyre pyrolysis char (AP-CO 2 ) and KOH-activated tyre pyrolysis char (AP-KOH) were 0.473 and 0.969 mmol g (cid:0) 1 , respectively.

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
