“…The maximum adsorption capacities of fluoride on Al 2 O 3 /BCF and LDH/BCF were 9.18 mg/g and 15.21 mg/g, respectively. However, the BET surface area of LDH/BCF is lower than that of Langmuir and Freundlich models [21] were applied to describe the fluoride adsorption process. By contrast, the experimental data of isotherm fitted well with the Langmuir isotherm model.…”

The removing of fluoride from water is highly desired from the viewpoint of environmental protection and sustainable development due to the adverse impacts on human and ecosystem. In this study, the hierarchical porous layered double hydroxide (LDH)/biomass carbon fiber (BCF) has been successfully fabricated by the combined sol-gel, carbonization and hydrothermal processes using sustainable bamboo fibers as raw material based on the assembly the LDH nanosheets on BCF surfaces. Structural characterization indicates that the LDH nanosheets were attached to the BCF surface via in situ crystal growth. N 2 sorption measurements show that the LDH/BCF has relatively uniform accessible mesochannel size of 3.56 nm, and the surface area is as high as 39.89 m 2 /g. The resulting LDH/BCF exhibit a noticeable enhanced adsorption capacity for fluoride removal compared to that of Al 2 O 3 /BCF, accompanied by 15.21 mg/g of the adsorption capacity. The presence of the high negative charge anions had negligible influence on fluoride adsorption. Importantly, recovery adsorption capacity for fluoride was obtained for LDH/BCF for 5 consecutive cycles without a significant decrease in its adsorption properties. Therefore, the current research can offer a green approach to fabricate LDH/BCF with hierarchical structures for efficient removing fluoride from water, and the fabricated LDH/BCF will be an excellent candidate for pollution control based on the synergistic effects of BCF and LDH, high adsorption properties with good reusability. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…The remarkable pH‐dependent immobilisation of Se(IV) may be owing to the negatively charged surface of nZVI in alkaline environment. It has been reported that the electrostatic repulsion between the Se(IV) and negatively charged surface may decrease the reactive sites for Se(IV) reduction [14]. Besides, the formation of the Fe(II)/Fe(III) hydroxide shell will also occupy the reactive sites on nZVI surface and decrease its reactivity, thus resulting in lower Se(IV) removal capacities.…”

“…Regarding chemical techniques, they include in situ burning, chemical solidification, and chemical dispersants which are commonly used to decrease oil spreading. 33,34 In situ burning is a successful method to remove oil from the water surface, but it harms air and water by releasing toxic dioxins, resulting in increased cancer risks of residents via the food chain and inhalation. 35,36 Also, the pollution generated by chemical solidification and chemical dispersants cannot be neglected.…”

Oil sorbents play a significant role in the treatment processes of oil spills, therefore, enhancing the oil-water separation capacity of sorbents has been charming the consideration of scientific researchers. To improve the properties of oil sorption and simplify the process of oil recovery, many advanced oil sorbent devices have been projected recently. Different types of materials are used as sorbents for oil-water separation, however, up to now, there is no review paper focused on textile (woven, knitting, and nonwoven) sorbents, and compared with them. In this review paper, the classification of textile fabrics, properties of surface wetting, fabrication methods of textile sorbents for oil spill cleanup, their properties, and recent applications in the field of oil cleanup are studied. We believe this review can serve as an essential reference for the formation of textile sorbents, their properties, and their applications in the field of oil spill cleanup.
