“…The mesoporous structure of FMAAM provided a large number of surface-binding sites for Tl(I), and the maximum capacity of FMAAM for Tl(I) adsorption was 78.06 mg/g. The results of the XPS analysis indicate that the main mechanisms for the removal of Tl(I) include oxidative precipitation, ion exchange, and surface complexation [61]. Fe 3 O 4 @TiO 2 , synthesized by loading iron oxide on the surface of reduced graphene oxide (RGO) nanosheets and subsequently coated with titanium oxide, had a maximum capacity of 673.2 mg/g of Tl adsorbed at pH 8.0.…”

Thallium is widely used in industrial and agricultural development. However, there is still a lack of systematic understanding of its environmental hazards and related treatment methods or technologies. Here, we critically assess the environmental behavior of thallium in aqueous systems. In addition, we first discuss the benefits and limitations of the synthetic methods of metal oxide materials that may affect the practicality and scalability of TI removal from water. We then assess the feasibility of different metal oxide materials for TI removal from water by estimating the material properties and contaminant removal mechanisms of four metal oxides (Mn, Fe, Al, and Ti). Next, we discuss the environmental factors that may inhibit the practicality and scalability of Tl removal from water. We conclude by highlighting the materials and processes that could serve as more sustainable alternatives to TI removal with further research and development.

In this study, a nanocomposite, Fe3O4/Fe‐Mn binary oxide/bentonite (FFMB), was synthesized, characterized and evaluated its adsorption behavior of azo Reactive Red 195 dye (RR‐195) in aqueous solution. The results of characterization (X‐ray diffraction, Fourier transform infrared spectroscopy, field emission scanning and transmission electron microscopies, vibration‐sample magnetometer, etc.) demonstrate that FFMB consists of Fe3O4 core and Fe2O3‐MnO2 binary oxide shell, which are distributed relatively uniformly on the exfoliated bentonite support with BET surface area of about 188 m2 g−1. It exhibits superparamagnetic properties with saturation magnetization of 39.6 emu g−1. The results of batch adsorption experiments show that the material has high ability of RR‐195 adsorption in terms of both adsorption rate and capacity. The adsorption efficiency was highest at pH 2–3. The adsorption process followed the pseudo‐second‐order kinetics and Langmuir isotherm models with a rather high maximum adsorption capacity of 163.4 mg g−1. Besides, Weber–Morris kinetic and Temkin isotherm models also provide useful insight into the adsorption mechanism. The material shows a good reusability. After 5 adsorption–desorption cycles the adsorption efficiency reached about 75% of the first cycle and the saturation magnetization decreased insignificantly. These results reveal that FFMB can become an alternative adsorbent for azo dye removal from wastewaters.
