β-Cyclodextrin network crosslinked by novel phosphonium-based tetrakiscarboxylic acid derived from PH3 tail gas: Synthesis and application for rapid removal of organic dyes from wastewater

Ultrathin Polymer Nanotubes Assembled from Side-Chain Amphiphilic Alternating Azocopolymers for the Potential of Highly-Efficient and Photo-Controllable Dye Removal

“…The facile synthesis imparts UTPNTs with a large number of positively charged surfaces, which is beneficial for the fast encapsulation of guest molecules. Figure f and Table S2 display the comparison in the adsorption performance of UTPNTs with other recently reported adsorbents, demonstrating a preferable adsorption capacity of UTPNTs toward anionic dye CR and the potential of UTPNTs on wastewater treatment and environmental remediation. − …”

“…In comparison, the adsorption constant for tubular absorbents of UTPNTs (7.79 × 10 –4 g mg –1 ) was smaller than that of the spherical absorbent of UTPVs (1.55 × 10 –3 g mg –1 ), proving the preferable adsorption activity of UTPNTs. Both large adsorption amounts and fast adsorption rates suggested the adsorption superiority of microscale UTPNTs, attributable to the large specific surface area and the siphonage effect of high-aspect-ratio tubular nanostructures. ,− Therefore, the distinct adsorption parameters (i.e., adsorption amounts, equilibrium time) for different hollow nanoarchitectures proved the photocontrollable adsorption performance toward anionic pollutants.…”

Adsorption of cationic/anionic dyes and endocrine disruptors by yeast/cyclodextrin polymer composites

“…The size of the dye is larger than the cavity of the β-CD, therefore only a part of the dye molecule can be accommodated within the cavity. 24 Furthermore, the cavities of multiple CDs create a macromolecular network, which enables the diffusion of dye molecules into the porous structure. 25 These properties promote the formation of host–guest complexes or inclusion complexes, allowing them to trap specific organic molecules.…”
