Fluorescence and Phosphorescence Chemical Sensors Applied to Water Samples

Abstract

Due to the outstanding characteristics of both fluorescence andphosphorescence signals, they are widely applied to the construction of chemicalsensors. The development of these sensors for the detection and quantification ofcompounds of environmental concern is an active research topic, daily enriched withthe contribution of new works in the area. This chapter provides fundamentals andpractical aspects of this type of sensors, focusing in those works devoted to quantifyboth organic and inorganic pollutants in environmental waters. The chapter isorganized upon the basic functional units of a chemical sensor. A few examples ofstrategies of evaluation involving multivariate chemometric analysis are alsodiscussed.
