Recently, climate change and air pollution are of the most important problems confronting the world. Hence, the present work is designed to provide an air purifier that can be re-utilized many times with high efficiency for several volatile pollutants. The air purifier fabricated from AC/TiO2 was used to investigate the performance of this filter towards the removal of volatile organic compounds (VOCs) from the air. The filter was composed of a mixture of fiber layers (TiO2, SiO2 and AC). The results indicated that the synergistic coupling of adsorption/oxidation technique is effective for removal of the air pollutants as well as for regeneration of the activated carbon to be extensional reused. The performance test of air purifier confirmed its high removal efficiency (98%). It was found that nearly up to 94% and 86% recovery of the filter activity could be achieved after the second and third cycles of treatment, respectively. From these results, AC/TiO2 filter still has the capability to remove and control extra gas pollutants indicating the synergistic coupling effect of TiO2 with the activated carbon. This filter concerns in developing an economic and feasible air purifier system to remove air contaminants for several times.

“…A great variety of adsorbents (natural or synthetic) have been used for the removal of organic substances from industrial air effluents and aqueous solutions. Activated carbons are considered as the most effective organics adsorbents with high surface areas (Andriantsiferana et al, 2015;Mohamed et al, 2015;Mohamed et al, 2016aMohamed et al, , 2016b. The adsorption capacity of activated carbon for the liquid adsorption of phenolic compounds depends on the solution conditions such as temperature, pH, ionic strength; and the adsorbate concentration (Magdy et al, 2018).…”

In recent years, interest has been focused on the removal of phenols from contaminated by using a variety of purification techniques. Adsorption of bio-industrial effluent on commercial activated carbon S23 was investigated at ambient conditions. In this wok, phenol and p-hydroxyl benzoic acid (PHBA) was studied as an example of the organic compounds present in the industrial effluent. The effect of temperature, pH, and the presence of inorganic salt NaCl on the pollutants adsorption were studied to give further comprehension of the optimal conditions of the organic compounds adsorption onto activated carbon. It was noted that the increase in temperature resulted in a decrease in phenols adsorption capacity by S23. Lower phenol adsorption was also observed at the solution pH 2 and 10, whereas, favourable adsorption was reached at neutral solution pH, and the coexisting inorganic salt NaCl exerts slightly positive effect on the adsorption process. The isotherms obtained at pH 2.2 and 3.5 (non-buffered solution) are very similar and showed a higher adsorption capacity compared with that obtained at pH 7 and 10 for PHBA which is more adsorbable than phenol. The kinetic of the adsorption processes can be better represented by the pseudo-second order. The results showed also that the total organic carbon (TOC) of the industrial effluent reduced for about 20 %. Freundlich, Langmuir and Jovanovic adsorption models were used for mathematical description of adsorption equilibrium of phenols. The results showed that the experimental data fitted very well to the Freundlich and Jovanovic models.
