Synergistic Adsorption-Photocatalytic Degradation of Tetracycline on Bi(OH)3
https://doi.org/10.1007/s11814-026-00684-5
Abstract
The synergistic adsorption-photocatalytic degradation is a simple and efective method for removal of pollutants from
wastewater. In this work, a bismuth-based photocatalyst Bi(OH)3 was synthesized by hydrothermal method. The prepared
samples were characterized by techniques like XRD, BET, SEM, TEM, XPS, UV-vis, TOC analysis, Zeta-potential and
electrochemical test. The adsorption performance was evaluated by investigations of adsorption isotherm, kinetics and
efects of photocatalyst dosage, initial TC concentration, solution pH value and adsorption temperature. The results showed
that Bi(OH)3 rapidly and efectively adsorbed and activated TC through hydrogen bonding, electrostatic interaction, the
pore flling mechanism, which were originated from the plenty of OHˉ in the structure of Bi(OH)3. The total TC removal
of 91% by synergistic adsorption-photocatalysis was obtained at condition as photocatalyst dosage of 0.5 g/L, initial TC
concentration of 50 mg/L, pH of about 5. Though the reusability of Bi(OH)3 photocatalyst need further improved in the
furture work, it can be considered a candidate material to remove antibiotics such as TC in wastewater.
