AI Article Synopsis
- Organic dyes are widely used but their leakage into the environment is a global issue due to toxicity and nonbiodegradability, prompting the need for effective removal technologies.
- This article discusses the synthesis of highly fluorinated conjugated microporous polymers that show promising adsorption properties, with a surface area of up to 1063 m²/g for removing cationic organic dyes from water.
- The fluorinated polymers demonstrate a strong adsorption capacity of 313 mg/g for crystal violet, outperforming traditional adsorbents and also function as proton channels in lipid membranes.
Article Abstract
Organic dyes are widely used in many applications. However, the leakage of organic dyes into the natural environment has become a severe and worldwide problem owing to their high toxicity and nonbiodegradability. Therefore, the development of effective removal technologies for organic dyes is required. In this article, we report the synthesis and adsorption properties of highly fluorinated conjugated microporous polymers based on pillar[]arenes. The polymers exhibited large Brunauer-Emmett-Teller surface areas of up to 1063 m g and selective adsorptive removal of cationic organic dyes from aqueous solutions. Comparison with the nonfluorinated polymers indicated that the adsorption mechanism mainly relies on the fluorine-cation electrostatic interaction. The maximum adsorption capacity reached 313 mg g for crystal violet, which is higher than those of conventional adsorbents. Additionally, the fluorinated polymers could function as proton channels when they were embedded into lipid membranes.

Population expansion, industrialization, urban development, and climate changes increased the water crisis in terms of drinking water availability. Among the various nanomaterials for nanoremediation towards water treatment, FeS-based nanocomposites have emerged as promising candidates in the adsorptive and photocatalytic removal of contaminants. This paper, therefore, evaluates the potential of FeS-based nanocomposites for environmental applications, more specifically the combined use of adsorption and photocatalysis.

Cellulose was extracted from rice straw waste by the intergrated technique of CHOH/HO, dilute alkali treatment and HO bleaching process, and rice straw-derived cellulose acetate was obtained by the acetylation reaction of cellulose. Flexible porous 3D biochars were constructed by the electrospinning, NaBH foaming and calcination process. Effects of calcination temperature, adsorption time, pH, pollutant concentration, interfering anions, and cycle times on the adsorption performance of 3D biochar were systematically investigated.

Although plant evolution has offered diverse biomass resources, the production of high-quality biochar from desirable lignocelluloses remains unexplored. In this study, distinct lignocellulose substrates derived from eight representative plant species were employed to prepare biochar samples under three different temperature treatments. Correlation analysis showed that only hemicellulose was a consistently positive factor of lignocellulose substrates to account for the dye-adsorption capacities of diverse biochar samples.
