摘要

Abstract: Sensors with optical transduction (optodes) based on plasticized poly(vinyl chloride) (PVC) bulk membranes incorporating a metal ion-selective ionophore, a hydrogen ion-selective chromoionophore and lipophilic anionic sites for the measurement of lead are presented. Different ionophores were used to design new optodes for environmental sensing properties. Since sufficient detection limits and excellent selectivities over alkali and alkaline earth metals are reached, these sensors can be used as monitoring devices for environmental relevant purposes. These reversibly working optodes show different dynamic ranges depending on the basicity of the involved chromoionophore and on the pH of the sample solution. Therefore, these sensors can be tailored to a specific application by varying these two parameters. Dynamic range, detection limit, response behavior, short-time repeatability, stability and selectivity of the optode systems are discussed.!22
