Dataset for oxytetracycline elimination via adsorption and LED-induced photocatalysis using a MIL-53(Al)@Biomass layered hybrid

Description

Oxytetracycline (OTC) is one of the most commonly used broad-spectrum antibiotics for treating both humans and livestock. However, when improperly disposed of, OTC poses a significant risk to water bodies due to its inhibitory effect on water nitrification and its impact on the microbiota. Therefore, various treatments are being investigated to address this pressing issue and offer a sustainable solution. Adsorption and advanced oxidation processes (AOP) over novel catalytic materials have drawn great attention for OTC removal. Major questions around these technological applications are related to their removal efficiency, catalyst stability and disposal after treatment cycles. Moreover, the elucidation of the underlaying kinetic and thermodynamic mechanisms governing these processes are also of paramount importance for process design and optimization. Accordingly, here we provide a complete dataset on the application of a novel MIL-53(Al)@Biomass layered hybrid (MIL-53(Al)@RH) for the removal of OTC from water bodies via adsorption and LED-driven photocatalysis. The MIL-53(Al)@RH was synthetized by a microwave-assisted solvothermal method enabling the in-situ hybridation of MIL-53(Al) with rice husk (RH). The dataset includes information on the pristine materials (MIL-53(Al) and rice husk), the MIL-53(Al)@RH, and a Carbon-Al obtained via pyrolysis of the saturated MIL-53(Al)@RH (affter adsorption). The information includes characterization results from several techniques viz. FTIR-ATR, XRD, SEM-EDX, N2-physisorption, Py-GC-MS, and pHZ. Moreover, data on BATCH adsorption experiments and AOP with MIL-53(Al)@RH is also provided. Adsorption data include information on the effect of MIL-53(Al)@RH dosage, solution pH, and kinetics measurements at different initial concentrations of OTC. Moreover, photocatalytic activity was tested at different oxidant doses (H2O2), OTC concentrations using a Led-light source. The data is organized in three folders: Folder 1: Hybrid and Carbon-Al characterization data: Include a complete set of characterization results for pristine materials, MIL-53(Al)@RH and recovered Carbon-Al after hybrid saturation. Here the reader will find the XRD patterns, N2 adsorption-desorption isotherms along with pore size distributions. Moreover, the pHz profile, SEM images, and a Py-GC-MS analysis on the catalyst decomposition are also provided. Folder 2: Adsorption data: This folder summarizes the results of the adsorption experiments including pH and MIL-53(Al)@RH doses, kinetic and equilibrium measurements. Folder 3: Photocatalysis data: This folder encloses the results of AOP for OTC elimination using MIL-53(Al)@RH as a photocatalyst. Readers will find results from the measurements of preliminary tests and AOP kinetics, catalyst stability cycles, and application of a carbon structure derived from MIL-53(Al)@RH as adsorbent and photocatalyst.
