“…Nevertheless, most approaches have practical drawbacks, including high costs, insufficient metal removal, the production and disposal of hazardous metal sludge, and unsuitability for water with traces of contaminants [11]. Currently, adsorption is the most effective process for the removal of contaminants from water compared to other methods due to its simplicity, cost-effectiveness with high efficiency, potential for regeneration, and sludge-free operation [12]. Recently, various low-cost non-conventional adsorbents have been utilized to sequester arsenic from contaminated water [2,3,[13][14][15][16][17].…”

A dynamic biosorption of arsenite in a fixed bed column packed with TiO2 impregnated pomegranate peel (PP@TiO2) has been investigated in this work, which is important to identify the effectiveness and affordability of an adsorbent in actual practice. To create an active adsorption site for As (III) ions, pomegranate peel powder (PP) was impregnated with TiO2. Under various operating parameters, the performance of a column packed with PP@TiO2 for adsorbing As (III) ions was evaluated. Breakthrough curve modelling showed that the bed depth service time (BDST) and Thomas models agreed well with the experimental data. The maximum column capacity of PP@TiO2 using the Thomas model was found to have resembled experimental value with high values of coefficient of determination. Therefore from these results, we may anticipate that PP@TiO2 can be a strong contender for the treatment of wastewater that has traces amount of the As (III) ion in a fixed bed system.

“…However, because of the need for costly equipment, lack of sensitivity, poor removal efficiency, and other factors, most of the preceding remedies can only be employed to a certain extent (Aryal et al, 2022;Aryal et al, 2019;Homagai et al, 2023;Saha et al, 2011). The adsorption method has become increasingly common due to the accessibility of less expensive components to produce inexpensive adsorbents (Bingol et al, 2004;Bashyal et al, 2023;Poudel et al, 2024). Agricultural residues (peels, seeds, husks, etc.)…”

In this work, Litchi chinensis seed powder has been chemically modified to charred Litchi chinensis seed powder (CLCS) for removal of Cr(VI) from the simulated wastewater. The adsorption capacity of CLCS for Cr(VI) was determined in batch experiment method. The materials were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and fourier transform infrared (FTIR) spectroscopy. Biosorption behaviour was investigated using isotherm and kinetic models. CLCS demonstrated a noteworthy adsorption capacity for Cr(VI), with a maximum adsorption capacity of 69.93 mg/g at pH 2.0. The Cr(VI) adsorption onto CLCS was found to follow pseudo-second-order kinetics and the experimental data best fitted with Langmuir isotherm model. According to the results, Cr(VI) can be removed from acidic wastewater using CLCS as an adsorbent. The results indicate that further studies and modification are necessary to improve the efficiency of the CLCS, and its feasibility at normal pH conditions.
