Project Abstract

This project involves the development of a novel electrochemical based voltammetric sensor for the determination of both nitrate and nitrite in potable water. The research methodology centres around the employment of nanostructured polyoxometallate (POM) functionalised surfaces as the sensing element within the proposed sensor. Two types of surfaces shall be investigated for their electrocatalytic properties, namely, POM doped conducting polymeric nanowires and POM nanoassemblies. Microfluidic channels etched in glass with an integrated electrochemical cell (fabricated in house) containing the sensing elements shall lead towards the development of an on-line device for continuous monitoring of environmental waters.
