Optical Fiber Sensors for Biocide Monitoring: Examples, Transduction Materials, and Prospects

Antifouling biocides are toxic to the marine environment impacting negatively on the aquatic ecosystems. These biocides, namely, tributyltin (TBT) and Cu­(I) compounds, are used to avoid biofouling; however, their toxicity turns TBT and Cu­(I) monitoring an important health issue. Current monitoring...

Description
Summary:Antifouling biocides are toxic to the marine environment impacting negatively on the aquatic ecosystems. These biocides, namely, tributyltin (TBT) and Cu­(I) compounds, are used to avoid biofouling; however, their toxicity turns TBT and Cu­(I) monitoring an important health issue. Current monitoring methods are expensive and time-consuming. This review provides an overview of the actual state of the art of antifouling paints’ biocides, including their impact and toxicity, as well as the reported methods for TBT and Cu­(I) detection over the past decade. The principles of optical fiber sensors (OFS) applications, with focus on environmental applications, and the use of organic chemosensors in this type of sensors are debated. The multiplexing ability of OFS and their application on aquatic environments are also discussed.
