  Lead-selective bulk optodes based on neutral ionophores with subnanomolar detection limits

  摘要：

  An optical sensor (optode) based on a plasticized poly(vinyl chloride) (PVC) bulk membrane incorporating a metal ion-selective ionophore, a proton-selective chromoionophore, and lipophilic anionic sites for the measurement of lead is presented. Different ionophores and chromoionophores were used to design a new optode for environmental sensing properties. The present optode system shows an especially excellent selectivity over alkali and alkaline-earth metals. The measuring range for lead was found to be 5.0 X 10(-9) to 5.0 X 10(-3) M at pH 5.68 with a corresponding detection limit of 3.2 X 10(-12) M. This reversibly working optode shows different dynamic ranges depending on the basicity of the chromoionophore and on the pH of the sample solution. Therefore, these sensors can be tailored to a specific application by varying the above mentioned parameters. Dynamic range, detection limit, response behavior, short-time repeatability, stability, and selectivity of the optode systems are discussed. Comparison with polarography shows good agreement.
