Topic Information

Dear Colleagues,

In recent years, with the emergence of a series of ecological and environmental problems, such as the intensification of the global greenhouse effect and the increase in the frequency of extreme weather, there is an urgent need to develop high-quality research results on pollutant adsorption–extraction techniques that are highly efficient and selective for pollutant extraction, and that are consistent with the principles of green chemistry.

The aim of this topic is to accept papers on the extraction and extraction of specific pollutants by chemisorption–extraction, using the chemical, biological and physical compound-related properties of the pollutants in reaction-mediated systems such as aqueous or ionic liquids, gas-phase and solid wastes, etc., and to provide a state-of-the-art forum for research in the field of extraction and adsorption, among other things.

This topic is geared towards a wide range of applications that are easily scaled up, suitable for green chemistry, continuous production and high separation and extraction efficiency, including impact assessment studies, efficient recycling and corresponding remediation strategies, in order to promote the scientific utilisation and effective mitigation of pollutants, to protect the ecological environment and human health, to safeguard the safety of industrial production, and to achieve low-cost operations.

We welcome innovative and cutting-edge articles and hope to build a platform for learning and exchange with you!

This study investigates the production of biochar from fresh wood shavings (B-WSF) and used wood shavings (B-WSU–animal litter) biomass through pyrolysis at 450 °C and explores its potential for NO2 adsorption at different temperatures from 22 °C to 250 °C. The biochars’ thermal stability, elemental composition, mineral content, textural properties, and surface chemistry were comprehensively analyzed using various techniques, including thermogravimetric analysis (TGA), ultimate analysis, proximate analysis, mineral composition analysis, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and NO2 adsorption experiments. The results indicate that biochars derived from WSF and WSU biomass possess high stability and exhibit significant changes in their elemental composition, surface functional groups, and textural properties compared to the raw biomass. The biochars demonstrated substantial NO2 adsorption capacities and reduction, with B-WSU biochar exhibiting higher adsorption capacity attributed to its higher specific surface area, mineral content, and functional groups. In addition, the results reveal distinct patterns in NO2 adsorption and NO release, with temperature playing a pivotal role in the process. At lower temperatures, NO2 adsorption on both biochars exhibits gradual increases, while higher temperatures facilitate immediate adsorption and subsequent reduction to NO. The adsorption of NO2 increased with increasing adsorption temperature, with B-WSU biochar achieving a maximum adsorption capacity of 43.54 mg/g at 250 °C, compared to 9.62 mg/g for B-WSF biochar. Moreover, XPS analysis revealed alterations in surface functional groups upon NO2 exposure, indicating enhanced surface oxidation and formation of nitrogen-containing species. In addition, differences in surface heterogeneity and mineral content influence NO2 adsorption behavior between the biochar samples. These findings highlight the potential of WSF biomass-derived biochar as an effective adsorbent for NO2 removal, offering insights into its application in air pollution mitigation strategies. The mechanism of NO2 adsorption involves chemisorption on oxygen-containing functional groups and physical adsorption, facilitated by the high specific surface area and pore volume of the biochar. Furthermore, the rich mineral content in B-WSU biochar explains its high adsorption capacity, demonstrating the potential for valorization of waste materials in the circular economy. Full article

Revolutionary technological advances have posed new challenges to humans, and modern technology needs to seek new breakthroughs. Imprinting technology, also known as template technology, is a technology based on the interdisciplinary development of polymer chemistry, biochemistry, chemical engineering, and materials science. The polymer prepared with imprinting technology, termed as imprinted polymer, has a memory effect on specific ions and can realize the selective recognition and enrichment of target species. Therefore, imprinting technology has great potential for application in water environment remediation and industrial wastewater treatment, especially for the treatment of low-concentration, toxic, and difficult-to-degrade heavy metal-containing wastewater. Herein, an overview of recent advances in imprinting technology in the field of adsorption and separation is presented, focusing on methods for the synthesis of imprinted polymers and their application to the separation and enrichment of metal ions in water. Finally, we propose several key issues that remain to be solved in the near future. Full article
