A review: Methods for removal and adsorption of volatile organic compounds from environmental matrixes

Abstract

The volatile organic compounds (VOCs) have toxic effect on human health and environmental matrixes. So, determination and removal VOCs from the environmental samples such as water, wastewater and air are very important as toxicology effect on humans. Many chemistry techniques such as; analytical methods for sorbents (extraction, adsorption), sole gel method, pervaporation, regenerative catalytic oxidation (RCO), recuperative catalytic oxidation (CO), adsorptive concentration-catalytic oxidation, photocatalytic oxidation (PCO), ozonation-catalytic oxidation and non-thermal plasma-catalytic oxidation, were used for removal and decreasing of VOCs from different matrix. This review study introduces the adsorbents and applied chemistry methods which were recently used in different works for removal of VOCs in air or water samples by scientists.

Removal of Benzene and Toluene from Synthetic Wastewater by Adsorption onto Magnetic Zeolitic Imidazole Framework Nanocomposites

“…The DR model is another isotherm equation that the laboratory data obtained followed this model with a high correlation coefficient. This model is generally used to describe the adsorption mechanism [ 50 , 51 ]. This model’s constant value of E may be used to determine whether the process is physical or chemical.…”

Integrated and Hybrid Processes for the Treatment of Actual Wastewaters Containing Micropollutants: A Review on Recent Advances

“…Table 3 shows how effectively conventional and advanced biological, adsorption, AOP, and membrane filtration processes could remove BOD, organic micropollutants (OMPs), total solids (TSs), and total organic carbon (TOC) from the wastewater. When opting for the most suitable treatment approach, factors such as process efficiency, operational simplicity, and adaptability must be considered [104,146]. Table 4 summarizes the advantages and disadvantages of some wastewater treatment processes.…”

Antifungal Graphene‐based Absorbers as Advanced Materials for Preventive Conservation of Cultural Objects

“…But what is predominant is the VOC‐IL interaction, since after the incorporation of the IL in the GAs, an important increase in the absorption was determined for all the examined VOCs. ILs like the one used for this study are known to have a remarkable affinity for VOCs [16] . As mentioned, C 16 MImCl induced a significant increase in hydrophobicity, turning the interaction with the VOC molecules stronger [17] .…”

“…ILs like the one used for this study are known to have a remarkable affinity for VOCs. [16] As mentioned, C 16 MImCl induced a significant increase in hydrophobicity, turning the interaction with the VOC molecules stronger. [17] Also, such IL favors the formation of strong hydrogen bonds with VOCs.…”
