Sol–gel electrode and coated-wire ion-selective electrode (CWISE) based on Schiff base as
a neutral carrier, was successfully developed for detection of Pb (II) in aqueous solution. The
sol–gel and CWISE exhibited linear response with Nernstian slope of 29.1 and 28.9
mV/decade, respectively, within the concentration ranges of 5.0× 10− 6 to 1.0× 10− 1molL−
1 lead ion for sol–gel and coated. The sol–gel and CWISE has shown detection limits of 3.0×
10− 6 and 5.0× 10− 6M, respectively. The electrodes exhibited good selectivities over a ...
