“…The Benesi-Hildebrand double reciprocal method is conducive to confirm the stoichiometry and kinetic parameters involved in the process of inclusion complex formation [27] . Here, the dependency-relationship between Fx absorbances and 2-HP-β-CD concentrations was analyzed using B-H double reciprocal method.…”

“…Various contaminants can be removed from aqueous solutions using membrane techniques, e.g., with polymer inclusion membranes which have been successfully used, among others, to separate metal ions [ 24 , 25 , 26 ] and dyes [ 27 , 28 , 29 ] and different pesticides from aqueous matrices [ 30 ]. PIMs were also applied for the remediation of pharmaceuticals and endocrine-disrupting substances from water systems [ 16 ].…”

“…They reported the extraction of 99% of analyzed synthetic dyes under optimized experimental conditions. Minhas et al [ 29 ] applied an ester derivative of calix[4]arene (EDC) as a carrier in polymer inclusion membranes consisting of CTA as a base polymer and 2-NPOE as a plasticizer and used the prepared membranes for extraction of cationic synthetic dyes (methylene blue, basic red, and Nile blue) from aqueous solutions. After optimization of various experimental parameters (pH of the donor and the acceptor phases, temperature, stirring speed, and concentration of membrane components and dyes in feed solutions), PIMs enabled the extraction of about 90% of dyes.…”

Pollution of the environment, including water resources, is currently one of the greatest challenges due to emerging new contaminants of anthropogenic origin. Of particular concern are emerging organic pollutants such as pharmaceuticals, endocrine disruptors, and pesticides, but also other industrial pollutants, for example, synthetic dyes. The growing demand for environmentally friendly and economical methods of removing emerging contaminants and synthetic dyes from wastewater resulted in increased interest in the possibility of using techniques based on the application of polymer inclusion membranes (PIMs) for this purpose. PIM-based techniques are promising methods for eliminating emerging contaminants and synthetic dyes from aqueous solutions, including wastewater, due to high efficiency, membranes versatility, ease/low cost of preparation, and high selectivity. This review describes the latest developments related to the removal of various emerging contaminants and synthetic dyes from aqueous solutions using PIMs over the past few years, with particular emphasis on research aimed at increasing the effectiveness and selectivity of PIMs, which may contribute to wider use of these methods in the future.

Pollution caused by the release of toxic heavy metals into the environment by industrial and farming processes has been regarded as a major problem worldwide. This has attracted a great deal of attention into restoration and remediation. Mercury is classi ed as a toxic heavy metal which has posed signi cant challenges to public and environmental health. To date, conventional methods for mercury detection rely on expensive, destructive, complex, and highly specialized methods. Evidently, there is a need to develop systems capable of easily identifying and quantifying mercury within the environment. In this way, organic-based colorimetric chemosensors are gaining increasing popularity due to their high sensitivity, selectivity, cost-effectiveness, ease of design, naked-eye, and on-site detection ability. The formation of coumarin-azo derivative AD1 was carried out by a conventional diazotization reaction with coumarinamine 1c and N,N-dimethylaniline. Sensor AD1 displayed remarkable visual colour change upon mercury addition with appreciable selectivity and sensitivity. The detection limit was calculated as 0.24 µM.Additionally, the reversible nature of AD1 allowed for the construction of an IMPLICATION type logic gate and Molecular Keypad Lock. Chemosensor AD1 displayed further sensing applications in real-world water samples and towards on-site assay methods. Herein, we describe a coumarin-derived chemosensor bearing an azo (N = N) functionality for the colorimetric and quantitative determination of Hg 2+ in organic and aqueous media.
