Polymer‐based chromogenic sensors for the detection of compounds of environmental interest

Abstract

The applications of functional polymers to different research fields have been increasing. An especially important application is the use of polymer‐based sensors for the chromogenic detection of compounds of environmental interest in water. Polymer matrix supports have been developed to improve the sensing capacity and performance of chromogenic sensors. Therefore, research in the area of sensor design and manufacturing for pollutant detection is increasingly interesting to many scientific communities ranging from biological and chemical sciences to engineering. This subject of this review is colorimetric sensors that enable the rapid and quantitative detection of different analytes within a laboratory setup. The applications of different types of polymer‐based sensors used in the chromogenic detection of compounds of environmental interest are reviewed and analysed. © 2021 Society of Industrial Chemistry.

Optical In Situ Monitoring of Acid Mine Drainage Remediation: Laboratory and Model Investigation

“…Temperature (Baleizao et al 2008), chloride (Steinbrück et al 2011b), carbon dioxide (Sipior et al 1996), sodium and potassium (Ast et al 2011), calcium (Shortreed et al 1996), ammonium (Strömberg 2008), and nitrate (Vallvey et al 2005) have all been monitored using optical sensing. A lot of optical sensors exist that detect compounds of environmental interest (Fang et al 2018; Urbano et al 2021), but they have not been used for environmental applications (Shanafield et al 2018). Optical sensors have been used to check the tightness of pipelines and geohazards monitoring (Joe et al 2018), as well as nitrogen dioxide gas phase measurements (Pan et al 2020) and groundwater tracer tests with heat transport (Drusová et al 2019).…”

Modelling Sorption and Transport of Gases in Polymeric Membranes across Different Scales: A Review

“…A multitude of applications are associated with the sorption and transport of gases and vapors in polymeric materials, such as membrane separation, carbon capture, polymer production and processing, packaging, volatile organic compound detection, thin-film coating, and environmental protection [1][2][3][4][5][6][7][8].…”
