Photocatalytic removal of the antibiotic Ciprofloxacin from aqueous solutions using Fe-dopedTiO2@Fe3O4 magnetic nanoparticles

Background & Aim: Antibiotics are stable compounds with low biodegradability that are generally not removable by conventional wastewater treatment processes. The aim of this study was to investigate the ability of Fe-doped TiO2@Fe3O4 magnetic nanoparticles in the presence of ultraviolet irradiation to photocatalytic removal of ciprofloxacin from aqueous solutions.  Methods: The sol-gel method ...

Removal of methylene blue from aqueous solutions using modified clay

Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...

Removal of Methyl Orange from Aqueous Solutions by Ferromagnetic Fe/Ni Nanoparticles

Herein, the removal of methyl orange (MO), a monoazo dye, from aqueous solutions was investigated using bimetallic ferromagnetic Fe/Ni nanoparticles (NPs) with the average particle size of 12-16 nm. The effect of contact time, pH, temperature, and Fe/Ni dosage on dye removal process was investigated. The results showed that 60 mg of Fe/Ni NPs at 25 oC and pH= 1 can remove 99.5% of 50 mg/L dye s...

Catalytic effect of Fe@Fe2O3 nanowires and Fenton process on carbamazepine removal from aqueous solutions using response surface methodology

Carbamazepine is one of the hydrophilic compounds identified in aquatic environments. Due to toxicity and bio-stability of this psychotropic pharmaceutical in the environment and humans, its removal efficiency and mineralization are important. In this study, synthesized Fe@Fe2O3 nanowires were applied to improve Fenton oxidation process using FeCl3.6H2</sub...
