Abstract
This work demonstrates that phenol and thiophenol, which are toxic to living organisms and the environment, can be effectively eliminated from water using selected commercially available ion exchange resins: IRA402, IRA900 and PWA5. This work fills the research gap by reporting for the first time an experimental study of phenol removal using IRA402 resin and thiophenol removal using IRA900 and PWA5 resins. The comparative analysis for the kinetics experiments were performed at pH 11. Under these conditions both phenol and thiophenol removal from water is highly efficient, and is mainly due to the ion exchange process between chloride ions attached to the quaternary functional group of the resin and phenol (or thiophenol). The studies have also shown a high efficiency of phenol and thiophenol desorption from the tested resins using a 4 % HCl solution. The experimental study showed that thiophenol sorption is less efficient on all tested resins than phenol sorption. Furthermore, the PWA5 resin with a triethylammonium group is less capable of removing both phenol and thiophenol than the IRA402 and IRA900 resins, which have trimethylammonium groups. The innovative nature of the work is the use of computational quantum chemistry methods to predict the results of experiments. DFT calculations, performed for the first time, model the ion exchange process between the studied resins and both phenol and thiophenol, and are in full agreement with the experimental data.
