Abstract

This study investigates the adsorption and photocatalytic degradation of fluoxetine using clinoptilolite (CLP)/TiO₂, NaX/TiO₂, and MIL-101 (Fe)/TiO₂ composite photocatalysts. The maximum monolayer adsorption capacity of fluoxetine followed the order CLP/TiO₂ (28.49 mg g⁻¹) < NaX/TiO₂ (87.50 mg g⁻¹) < MIL-101(Fe)/TiO₂ (222.4 mg g⁻¹) under optimum pH of 9, an adsorbent dosage of 0.5 g L⁻¹, and 25 °C. The equilibrium time for the fluoxetine sorption using CLP/TiO₂, NaX/TiO₂, and MIL-101(Fe)/TiO₂ was 120 min, 50 min, and 20 min, respectively. The adsorption data of fluoxetine followed the Pseudo-second-order kinetic and Freundlich isotherm models. The removal efficiency of fluoxetine (50 mg L⁻¹) using MIL-101(Fe)/TiO₂, NaX/TiO₂, and CLP/TiO₂ during adsorption/UV irradiation & adsorption/visible light irradiation was 91.8 & 87.8%, 66.5 & 39.2%, and 48.3 & 21.9% within adsorption equilibrium time/120 min irradiation time. The MIL 101(Fe)/TiO₂ catalyst regenerated for five runs without significant changing in the photocatalytic removal efficiency. The degradation efficiency of fluoxetine using MIL-101 (Fe)/TiO₂ was higher than that of CLP/TiO₂, and NaX/TiO₂ through the highest adsorption capacity of MIL-101 (Fe) and synergistic photocatalytic role of MIL-101 (Fe) and TiO₂ under UV and visible light irradiation during adsorption/photocatalysis combined method. The efficient degradation of fluoxetine using MIL-101 (Fe)/TiO₂ under visible light at a shorter time confirmed the use of the synthesized photocatalyst for the treatment of pharmaceutical wastewater in the future.
