<p>The current study work's contribution relates to the removal of xylene using an adsorbent with modified surfaces made from a naturally occurring substance called avocado seed. With the aid of a muffle furnace heated to 600⁰c, this was converted to become activated carbon. Activated carbon is modified on the surface using titanium di oxide (Tio2). This surface modification demonstrated significant performance in the designated surface area of 67.35 m2 g-1. The varied levels of xylene concentration drop at three distinct temperatures 30, 60, and 90⁰C were visible. Applying the Thomas and Adams-Bohart to describe equilibrium adsorption data resulted in the model having the highest R2 values for describing equilibrium isotherm data. SEM patterns captured the degree of the surface modification with increased porosity; however, XRD and FTIR analyses of the surface modified adsorbent did not reveal any structural distortion. This thorough analysis resulted in the efficient removal of 93% of xylene by cost-effective adsorbent</p>

“…The WHO set Benzene (1ppb), Toluene (180ppb), Ethylbenzene (80ppb), and Xylene as the permitted limits (75 ppb). The BTEX suite of measurements is helpful [5]. There are a lot of VOCs present in normal metropolitan areas, which are given off by everything from paint to car exhaust.…”

Removal of BTEX (Benzene, Toluene, Ethyl benzene and Xylene) from aqueous solutions using surface-modified zeolite

<p>BTEX, also known as benzene, toluene, ethyl benzene, and xylene, is a common gasoline oxygenate. The contamination of groundwater and surface water with BTEX and its primary breakdown product has drawn a lot of attention. However, surface-modified zeolite's sorption mechanisms and affinity for BTEX can be employed to potentially remove these toxins from water. Tert-butyl alcohol (TBA) was utilized to alter the morphology of the adsorbent. Based on the findings, it can be concluded that zeolites have a greater capability for removing emerging chemicals. Some of the emerging compounds' relatively large dimensions limit their natural ability to lower values. Gas chromatography was used to determine the BTEX concentration decrease range. The Yoon-Nelson and Adams-Bohart model's use of mathematical modelling to determine the efficacy of the column's adsorption. The model with the highest R2 values for characterizing equilibrium isotherm data describes equilibrium adsorption data. To gain an understanding of the shape, pore structure, and active sites, the characterisation is concentrated on quantitative analysis using XRD, qualitative analysis using FTIR, and optical study using SEM.</p>
