“…However, the application of chemical solvents is constrained by the concerns related to physical characteristic limitations, such as viscosity, corrosiveness, and higher energy consumption (Choi et al, 2014). Ionic liquids (IL) emerge as a promising solvent for H 2 S removal, being vapourless, thermally stable, reusable, and recognised as environmentally friendly solvents (Beigi et al, 2018). IL exist in a liquid form as molten salts and are composed of both anions and cations.…”

The imidazolium-based supported ionic liquids (IL) in activated carbon (AC) is an exciting strategy for developing new adsorbents for H 2 S removal from biogas. In this work, the influence of IL on AC was discovered by examining the effect of ultrasonic stirring as an impregnation method, AC particle size and IL anion type. AC300μm- [Bmim] Cl-U5 demonstrated the highest H 2 S adsorption capacity of 8.25±0.38 mg H 2 S/g and was obtained through [Bmim] Cl impregnated on 300 μm AC size through the ultrasonic stirring for five minutes at room temperature. The adsorption/desorption study confirmed the regeneration ability of AC300μm-[Bmim]Cl-U5 up to three cycles with a maximum adsorption capacity of 14.24±0.43 mg H 2 S/g. The SEM images confirmed the presence of IL on the AC surface and were further explained through BET analysis. TGA measurement indicated the thermal stability of pristine IL, the fresh and exhausted adsorbent. Therefore, this study proved the potential of ultrasonic-assisted supported IL as a promising adsorbent for H 2 S removal from biogas that exhibits excellent properties in high adsorption capacity and thermal stability.

“…The people which were worked with chemicals such as VOCs, toxic heavy metals, and toxic gases (H2S) must be determined in biological matrixes and considered as an important feature in the HSE-MS system. So, evaluation and determination of this pollution in workers, waters and gases with analytical technique (Bagheri Hosseinabadi et al, 2019; Jamshidzadeh & Shirkhanloo, 2019; Miranbeigi et al, 2018; Mirzahosseini, 2019; Pasban & Nonahal, 2018; Paydar & Faghihi Zarandi, 2019) must be done for chemical industries as the main indicators.…”

By integrated management system (IMS) based on integrated main indicators (IMI), the quality of health, safety and environmental management specifically for chemical industries was well increased. This study aimed to evaluate and compare integrated and efficient indicators in two chemical industries in Iran by health, safety, and environment (HSE) management system (MS). The integrated indicators were divided into HSE domains in the form of a questionnaire by proposed method and the weight of each of them was calculated from 101 features in the field. A list of criteria, sub-criteria, and integrated indicators was first prepared for assessing the performance of the HSE-MS system, and Delphi was finalised with the help of experts, and then the results were weighed by ANP and DEMATEL methods for two companies. Finally, 101 integrated and efficient indicators were extracted for performance evaluation to demonstrate the application of the DEMATEL, ANP method to select effective indicators in measuring HSE-MS performance in two chemical industries. In this study, the mean scores per weight of HSE indicators for chemical industries A and B increased from 2.38 to 2.79 and 1.84 to 2.056 in the beginning of 2017 up to the end of 2018. The mean score of HSE indicators for companies A and B were archived (2.65 and 2.93) and (1.95 and 2.16), respectively, in the spring/winter of 2017 and 2018. So, HSE-MS and IMS help chemical industries to improve HSE and management systems to achieve high-quality industry in different options, especially in human sources. Although in this study all trends of HSE indicator had a moderate phase with positive rate from spring 2017 up to winter 2018 for two companies A and B but company B moved slowly as compared to company A.

“…Also, the exposure to toxic metals (Pb, hg, as, Mn, Al) is dangerous for human health due to the combustion of leaded gasoline. Many metal aerosols and gas pollutants created from crude oil and must be removed from oil before enter to air [6,7]. Moreover, sometimes, the heavy metals generate by recycled products such as battery factories [8,9] and high exposure in air threatens people's health.…”

In this study, the enrichment and novel sorbent based on functionalized bimodal mesoporous silica nanoparticles (HS-UVM 7 and NH 2 -UVM 7 ) was used for removal of lead aerosols pollution from air by solid liquid gas phase extraction method (SLGPE). In bench scale set up, the lead aerosols [(Pb (NO 3 ) 2 , PbO] was generated by dispersive aerosols generator system (DAGS) and removed from air by reaction loop (RL) / impinger trap (IT) in a liquid phase which was mixed with nano adsorbent in optimized pH. The effect of parameters such as, flow rate, volume of liquid phase, time stirring, temperature, concentration, pH and amount of sorbent (mg) were studied and evaluated by flame atomic absorption spectrometry (FAAS). In optimized conditions, the adsorption capacity of HS-UVM 7 and NH 2 -UVM 7 for Pb(NO 3 ) 2 aerosols was obtained 255.6 mg g −1 and 177.6 mg g −1 , respectively which was more than UVM 7 . The lead oxides aerosols (PbO) were extracted only by HS-UVM 7 at acidic pH with the adsorption capacity of 271.2 mg g −1 . The characterization of SEM, XRD, TEM, and FTIR showed that the HS-UVM 7 has beneficial surfaces for removal of (Pb (NO 3 ) 2 and PbO aerosols from the air by SLGPE method at pH = 5. The method validation was confirmed by standard addition and NIOSH method.
