Abstract
A novel ion-selective membrane electrode for the determination of phosphate anions. This device possesses an excellent selectivity for phosphate over many common anions such as sulfate, chloride, bromide, iodide, nitrate, and acetate. The unique feature of this electrode is the use of a di-substituted aryl tin compound as the membrane active material. The incorporation of either dibenzyltin dichloride or bis-p-methylbenzyltin dichloride in a plasticized poly(vinyl) chloride membrane results in a selective membrane electrode for phosphate.
