“…The researches showed that the chemical and the physical properties of sorbents affected adsorption and removal efficiency of VOCs pollutions in air (Teimoori et al 2020;Lara-Ibeas et al 2020;Mozaffari et al 2020). Recently, the different ILs, TSILs and ILs coated on the carbon structure were used for extraction of toxic metals, VOCs and other aromatic compounds in the different matrixes such as, waters and air (Salar-García et al 2017;Santiago et al 2016;Mahboobeh Yousefi et al 2018;Belenguer-Sapiña et al 2019;Rangkooy et al 2019). Moreover, the different sorbents and techniques such as the fullerene nanoparticles based on UV-photocatalytic oxidation method (UV-PCOM), the functionalized graphene-trimethoxyphenyl silane with sorbent gas extraction (FGTMPhS-SGE), the multi-walled carbon nanotubes by gas chromatography (MWCNTs-GC-FID), the static headspace with GC-MS (SHS-GC-MS) and the nanographene (NG) or CNTs as solid-phase extraction based on the GC or cold vapor-atomic absorption spectrometry (SPE-GC-FID/CV-AAS) were used for the removal of hazardous pollutants such as BTEX, mercury vapor and H 2 S gas from air (Ebrahimi 2019;Miran Beigi and Shamsipur 2019;Mostafavi and Ebrahimi 2019;Kazemi and Yaqoubi 2019;Arjomandi 2019).…”

Human exposure to high levels of benzene in the air leads to toxic effects in human body and so, it is necessary to determine by high sensitivity and precision methodology. A simple and efficient method based on the triphenyl(3-sulfopropyl) phosphonium p-toluenesulfonate as TSIL was coated on multi-walled carbon nanotubes ([TPhPP][SUTO]-MWCNTs) and used for benzene vapor removal from air. By procedure, the tube and headspace sorbent based on solid-phase extraction coupled to gas chromatography-flame ionization detector (ST/HS-SPE-GC-FID) was used in dynamic and static systems, respectively. All effected factors including the flow rate, the mass sorbent, benzene concentration, the contact time and the temperature were optimized in dynamic and static systems. Chamber was designed for benzene generation in pure air, and then, mixture of gas moved to passive thermal desorption tubes (ST) or head space (HS) in the glass chromatography vials as dynamic and static methods, respectively. The benzene was eliminated from air with 10 mg of ([TPhPP][SUTO]-MWCNTs); C 28 H 29 O 6 PS 2 -MWCNTs, 1:1] at 25 °C, desorbed from the sorbent at 95 °C and measured by GC-FID. The removal efficiency and the absorption capacity of [TPhPP][SUTO]-MWCNTs for benzene were obtained to be 98.8% and 169.6 mg g −1 at flow rate of 300 ml min −1 . The chemical adsorption of benzene from air was related to π-π, electrostatic, hydrophobic interactions between aromatic chains of TSILs with the benzene molecules, and it caused the increase the removal efficiently of benzene vapor from air more than 95%. The results were validated by GC-MS and spiking of real samples which was determined by GC-FID.
