“…The detection and quantification of diclofenac, a highly efficient and widely consumed anti-inflammatory drug, in water and wastewater samples (in the range 0.3-15.9 mg L −1 ) have also been developed [165] by resorting to a polycyclodextrin containing a fluorescent dye. The optimal concentration of the sorbent was found to be 50 g mL −1 , and the limit of quantification of diclofenac was 0.3 mg L −1 .…”

Chemical pollution of water has raised great concerns among citizens, lawmakers, and nearly all manufacturing industries. As the legislation addressing liquid effluents becomes more stringent, water companies are increasingly scrutinized for their environmental performance. In this context, emergent contaminants represent a major challenge, and the remediation of water bodies and wastewater demands alternative sorbent materials. One of the most promising adsorbing materials for micropolluted water environments involves cyclodextrin (CD) polymers and cyclodextrin-containing polysaccharides. Although cyclodextrins are water-soluble and, thus, unusable as adsorbents in aqueous media, they can be feasibly polymerized by using different crosslinkers such as epichlorohydrin, polycarboxylic acids, and glutaraldehyde. Likewise, with those coupling agents or after substituting hydroxyl groups with more reactive moieties, cyclodextrin units can be covalently attached to a pre-existing polysaccharide. In this direction, the functionalization of chitosan, cellulose, carboxymethyl cellulose, and other carbohydrate polymers with CDs is vastly found in the literature. For the system containing CDs to be used for remediation purposes, there are benefits from a synergy that arises from (i) the ability of CD units to interact selectively with a broad spectrum of molecules, forming inclusion complexes and higher-order supramolecular assemblies, (ii) the functional groups of the crosslinker comonomers, (iii) the three-dimensional structure of the crosslinked network, and/or (iv) the intrinsic characteristics of the polysaccharide backbone. In view of the most recent contributions regarding CD-based copolymers and CD-containing polysaccharides, this review discusses their performance as adsorbents in micropolluted water environments, as well as their interaction patterns, addressing the influence of their structural and physicochemical properties and their functionalization.

“…A cross-linked CD-based polymer with enhanced affinity for diclofenac (a nonsteroidal anti-inflammatory drug considered an emerging pollutant) was used to quantify the analyte in a municipal wastewater sample (Xiao et al, 2015). The method was based on the competitive displacement of fluorescein (a fluorescent dye) by the target analyte monitored by fluorescence polarization.…”

The development of Green Analytical Chemistry (GAC) methods is one of the most active areas of Green Chemistry. Especially relevant are GAC methods devoted to the detection and quantification of environmental pollutants, because they should not pollute the environment more than the analyte to be determined. While considerable attention has been paid to develop environmentally friendly alternatives for the first stage of the global analytical process (e.g., sample preparation techniques), relatively fewer works are dedicated to implement green approaches for obtaining the analytical signal. Current strategies that are based on the principles of Green Chemistry for the determination of common organic pollutants in natural waters are detailed. The review collects and discusses selected publications from about the last 5 years relating to the topic, highlighting the role of multivariate calibration as a modern and very useful tool to achieve the pursued objectives.

“…CD is composed of six, seven, or eight glucose units and has a cone-shaped structure with a hydrophilic exterior and a hydrophobic interior cavity. Among them, β-CD is the most widely used one because of its stable chemical structure, high water solubility, and wide host–guest inclusion complex via non-covalent bonding. − It is found that β-CD/PAN membranes have moderate water-absorbing capacity but a fast water transport rate, meaning that the liquid sweat can be absorbed and drawn out quickly. The moderate water-absorbing capacity of β-CD/PAN also imparts good antistatic properties to it.…”

Breathable and moisture-wicking membranes have attracted increasing attention due to their capability of providing a drier and cooler microclimate to satisfy the comfort of wearing. Despite being a widely used textile, unsatisfactory breathability and poor antistatic properties of polyacrylonitrile (PAN) remain a serious challenge. Herein, breathable, moisture-wicking, and antistatic fibrous membranes are prepared via electrospinning by introducing a hydrophilic small molecule β-cyclodextrin into PAN. By regulating the content of β-CD, fibrous membranes with tunable porous structures and flexible hydrophilicity are obtained. Significantly, the effect of pore size, hydrophilicity, and water capacity on the breathable, moisture-wicking, and antistatic performance has been investigated. Ultimately, the 125CD/PAN membrane with a mean pore size of 3.96 μm and a moisture regain of 6.72% exhibits the best equilibrium of breathable (water vapor transmission of 3.35 kg/(m 2 day), which is 88.6% of the WVTR measured without obstruction) and moisture-wicking (over 4 times than that of cotton) performance, as well as the best antistatic behavior (meeting the standard of non-durable antistatic textiles class C), which makes it an appropriate candidate in various applications, especially for the wearing comfortability of PAN textile.
