Date palm fiber agro-waste biomass for efficient removal of 2,4,6-Trichlorophenol from aqueous solution: Characterization, Kinetics, Isotherms studies and Cost-effective analysis
This study proposes using date palm biomass to remove emerging industrial contaminants, such as 2,4,6-Trichlorophenol (2,4,6-TCP) from water, promoting sustainable waste utilization and a more cost-effective technology. To investigate the potential of using raw date palm fiber and Triethylamine-modified date palm fibers (RDPF and TEA–MDPF) for 2,4,6-TCP removal in batch adsorption experiments. The residual concentration of 2,4,6-TCP in the effluents was examined using UV–visible spectroscopy. The structural and chemical composition of the raw and modified biomass materials was determined using various techniques, including BET, FTIR, Elemental analyzer (CHN), Particle size analysis, FESEM-EDX, and TGA analysis. The optimal pH for the highest 2,4,6-TCP uptake capacity in batch equilibrium adsorption studies was found to be 2.0 for RDPF and 6.0 for TEA-MDPF biomass. The sorption kinetics of 2,4,6-TCP onto both adsorbents was excellent, designated by the pseudo-second-order (R2 = 0.93–0.99) and Elovich models (R2 = 0.86–0.97). This indicates that adsorption was regulated by chemisorption. The results of the experiment exhibited a good correlation (R2) between the PSO and the maximum (qm) uptake capacities of the Langmuir isotherm model for the remediation of 2,4,6-TCP from aqueous media, which was 115.50 mg/g and 191.75 mg/g for RDPF and TEA-MDPF, respectively. TEA-MDPF biomass exhibits superior adsorption capacity compared to RDPF, making it a promising candidate for the remediation of 2,4,6-TCP from aqueous contaminated wastewater.
The date palm tree is extensively cultivated in Middle Eastern countries such as Saudi Arabia, generating a large amount of waste in the form of leaves, seeds, and fibrous materials.
