Cetylpyridinium chloride as a titrant for potentiometric titration of uranyl ion

Abstract

The possibility of determination of UO22+ in the form of uranyl benzoate anion by the potentiometric titration technique is presented. Cetylpyridinium-selective electrode have been successfully applied in the potentiometric measurements of uranium and the obtained results showed good performance of this electrode. The cetylpyridinium-selective electrode based on the PVC matrix was plasticized with o-nitrophenyl octyl ether and cetylpyridinium tetraphenylborate was used as ionophore. The produced electrode showed good potentiometric characteristics such as low detection limit of cetylpyridinium cation, wide concentration range, and reasonable response time.
