Adsorptive removal and photocatalytic degradation of organic pollutants using metal oxides and their composites: A comprehensive review

The combination of magnetic nanoparticles and metal–organic frameworks (MOFs) has demonstrated their prospective for pollutant sequestration. In this work, a magnetic metal–organic framework nanocomposite (Fe3O4@AMCA-MIL53(Al) was prepared and used for the removal of U(VI) and Th(IV) metal ions from aqueous environment. Fe3O4@AMCA-MIL53(Al) nanocomposite was characterized by TGA, FTIR, SEM-EDX, XRD, HRTEM, BET, VSM (vibrating sample magnetometry), and XPS analyses. A batch technique was applied for the removal of the aforesaid metal ions using Fe3O4@AMCA-MIL53(Al) at different operating parameters. The isotherm and kinetic data were accurately described by the Langmuir and pseudo-second-order models. The adsorption capacity was calculated to be 227.3 and 285.7 mg/g for U(VI) and Th(IV), respectively, by fitting the equilibrium data to the Langmuir model. The kinetic studies demonstrated that the equilibrium time was 90 min for each metal ion. Various thermodynamic parameters were evaluated which indicated...

Azad Islamic UniversityReceived August 6, 2001A simple and rapid technique for the separation and preconcentration of lead in water and biological sampleshas been devised. Preconcentration is based on the deposition of analyte onto a column packed with dithizoneimmobilized on sodium dodecyl sulfate coated alumina at pH ≥ 3. The trapped lead is eluted with 5 mL of 4-M nitric acid and determined by flame atomic absorption spectroscopy. A sample of 1 L, results in apreconcentration factor of 200, and the precision at 20 µg L
