This paper presents the results of study on the removal of methyl tert–butyl ether (MTBE) from aqueous solution containing 0.00143(gr\mL) of MTBE by using exfoliated graphite (EG) as adsorbent. Experiments were carried out in batch mode and the effects of several affecting factors on the removal of MTBE were evaluated. Also, the effect of ultrasound irradiation on adsorption of MTBE was investigated. Results showed an efficient removal of MTBE from aqueous solution could be achieved by implementing ultrasound facilitated adsorption process using EG. In controlled conditions maximum removal percentage of 97% was achieved for MTBE and it was found that applying ultrasonic irradiation had a considerable positive effect on the removal of MTBE from its aqueous solution.<\div>

The buckling behavior of functionally graded carbon nanotube–reinforced composite (FG–CNTRC) plates resting on Winkler–Pasternak elastic foundations under in–plane loads for various temperatures is investigated using element–free Galerkin (EFG) method based on first–order shear deformation theory (FSDT). The modified shear correction factor is used based on energy equivalence principle. Carbon nanotubes (CNTs) are embedded in polymer matrix and distributed in four types of arrangements. The temperature–dependent material properties of an FG–CNTRC plate are assumed to be graded along the thickness direction of the plate and estimated through a micromechanical model based on the extended rule of mixture. Full transformation approach is employed to enforce essential boundary conditions. The modified shear correction factor is utilized based on energy equivalence principle involving the actual non–uniform shear stress distribution through the thickness of the FG–CNTRC plate. The accuracy and convergency of the EFG method is established by comparing the obtained results with available literature. Moreover, the effects of elastic foundation parameters are investigated for various boundary conditions, temperatures, plate width–to–thickness and aspect ratios, and CNT distributions and volume fractions. Detailed parametric studies demonstrate that the elastic foundation parameters, CNT distributions along the thickness direction of the plate and the temperature change have noticeable effects on buckling behavior of carbon nanotube–reinforced composite (CNTRC) plates.
