Adsorption-Desorption of BTX (Benzene, Toluene and O-xylene) on Fe, Fe-Al Pillared Clay

Abstract

The studies are conducted in laboratory to determine the adsorption-desorption behavior of BTX (benzene, toluene and o-xylene) in gas phase on Fe, Fe-Al pillared clays adsorbents. In experimental conditions of constant atmospheric pressure, initial concentrations with an increasing volume (0.5 -2 ml) injected benzene (2.25), toluene (1.89) and o-xylene (1.66) μmol/L at T (40˚C, 60˚C and 80˚C), and the adsorption increases with increase of temperature, indicating that the adsorption process would be a chemical adsorption rather than physical one. The results are shown that the BTX adsorption data fitted very well (R 2 > 0.

Chromogenic detection of xylene isomers and luminogenic chemosensing of o-xylene employing a new macrocyclic cobalt complex: synthesis, and X-ray crystallographic, spectroscopic and computational studies

“…They are good alternatives due to the rapid electron and energy transfer employed in these methods or due to the induction of a colour change in the presence of the xylene to afford a fast response alongside a high accuracy towards the particular chemosensor molecule. 5–14 Table S1 (ESI†) 10–21 presents some important fluorescent materials that have been designed for xylene sensing. While some colourimetric sensor arrays are designed for xylene detection in the gas phase, no colourimetric sensors have been reported to detect and distinguish xylene isomers in the liquid phase.…”
