ABSTRACT
A silver-selective optode membrane incorporating hexathia-18-crown-6 for cation recognition and a lipophilic chromoionophore 1,2-benzo-3-octadecanoylimino-7-diethylaminophenoxazine for transduction has been prepared. The PVC membrane composition was optimized to result in the largest working concentration range. The response range of the proposed optode is 5.0�10-9�5.0�10-5 mol L-1 Ag+ with a limit of detection of 1.0�10-9 mol L-1. The probe works well at pH 5.0 and revealed small ion interference and good selectivity, reproducibility and stability.
