Alkylbenzenesulfonate Ion Selective Electrode Using Ferroin Salt in Polyvinyl Chloride Matrix

Abstract
An alkylbenzenesulfonate ion selective electrode has been made by incorporating the sulfonate -ferroin complex into a polyvinyl chloride matrix. The sulfonate concentration of 10−6 - 10−2 M is determined in the presence of 10 4 M of sulfate, phosphate, nitrate and chloride ions.
