摘要：
Membranes for optically sensing Ag+ and Hg2+ based on plasticized poly(vinyl chloride) (PVC) containing a metal ion-selective ionophore, a hydrogen ion-selective chromoionophore, and lipophilic anionic sites are presented. Different dithiocarbamate ionophores have been used to develop novel optical sensors for environmental analysis. Optode membranes based on the ionophore methylene bis(diisobutyldithiocarbamate) (MBDiBDTC) reversibly respond to Ag+ and Hg2+ and show extremely high selectivities over Li+, Na+, K+, Mg2+, Cu2+, Cd2+, and Pb2+. The detection limit for Ag+ is 2.5 x 10(-9) M at pH 4.7. The dynamic range, response behavior, reversibility, and selectivity of the optode membranes are discussed.
