“…11(a), the spectra of CD-functionalized ZSM-5 retained most of the characteristic peaks of b-CD and did not exhibit any of the characteristic peaks of ZSM-5. 45 FTIR spectroscopy was also used to ascertain the formation of the CDZ-CUR inclusion complex. CDZ-CUR complexes prepared by methanol reux appeared as amorphous substances whose colour was lighter than that of curcumin.…”

“…Therefore, modification of natural zeolites has been attempted to address the issue. 19,20 Macrocyclic compounds playing an increasingly important role in the treatment of Pillararene was initially discovered by Ogoshi in 2008. 21 It has a tubular morphology compared with other macrocyclic molecules such as crown ether, 22 cyclodextrin, 23−25 calixarene, 26,27 and cucurbituril.…”

“…Natural zeolite has been widely used in the aqueous treatment of environmental contaminants because of its wide variety, abundant reserves, low price, and simplicity of processing technology. , Zeolite has a unique structure comprising an aluminosilicate skeleton and abundant intracrystalline pores, resulting in strong ion exchange and adsorption properties. , However, zeolites exhibit a permanent negative electrical structure due to isomorphous replacement, which results in weak adsorption of organic anions. Therefore, modification of natural zeolites has been attempted to address the issue. , …”

A novel quaternary cationic pillar[5]arene-modified zeolite (WPA5/zeolite) was prepared via charge interaction between the cationic WPA5 and natural zeolite and characterized by scanning electron microscopy (SEM), Fourier transform infrared absorption spectroscopy, X-ray diffraction, solid-state nuclear magnetic resonance, and thermogravimetric (TG) analysis. The effects of zeolite particle size, WPA5 concentration, adsorption time, initial concentration, and pH on the removal of methyl orange (MO) were studied. The SEM and XRD results revealed a strong interaction between WPA5 and natural zeolite, and the modified composites showed novel microscopic morphology and structural properties. TG analysis indicated excellent thermal stability of the composite. MO was removed via electrostatic adsorption, and the removal efficiency was 84% at an initial concentration of 100 mg/L. Increase in the initial dye concentration enhanced the adsorption capacity of WPA5/zeolite and decreased the removal of MO. Based on the adsorption kinetics, the pseudo-second-order model (R2 = 0.998) described the kinetic behavior of MO on WPA5/zeolite. In addition, UV and fluorescence spectra revealed that MO and WPA5 are complexed by a 1:1 complex ratio, and the binding constant between them was 12 595 L·mol–1. NMR and molecular docking also verified their interaction. Therefore, the potential application of the prepared composite includes removal of organic anionic dyes.

“…However, ACs are granular or particulate solids that are better suited for packed columns rather than clothing or other household items, and their regeneration often requires harsh treatments. Alternatives to ACs, particularly those that combine superior performance, facile regeneration, and straightforward integration with consumer products and/or textiles, are desirable targets. − …”

Cotton Fabric Functionalized with a β-Cyclodextrin Polymer Captures Organic Pollutants from Contaminated Air and Water

et al. 2016

Cotton fabric is covalently functionalized with a porous β-cyclodextrin polymer by including the fabric in the polymerization mixture. The resulting functionalized fabric (CD-TFP@cotton) sequesters organic micropollutants, such as bisphenol A, from water with outstanding speed and a capacity 10-fold higher than that of untreated cotton. The functionalized fabric also readily captures volatile organic compounds (VOCs) from the vapor phase more quickly and with a capacity higher than that of untreated cotton as well as three commercially available fabric-based adsorbents. Volatile adsorbed pollutants were fully extracted from CD-TFP@cotton under reduced pressure at room temperature, permitting simple reuse. These properties make cotton functionalized with the cyclodextrin polymer of interest for water purification membranes, odor controlling fabrics, and respirators that control exposure to VOCs. This functionalization approach is scalable, likely to be amenable to other fibrous substrates, and compatible with existing fiber manufacturing techniques.
