Hydrogen peroxide electrodes based operation

While potentiometric enzymatic electrodes for detection of phosphate have been developed [121,122], no application has been made of these to water analysis because of the relatively poor sensitivity. However, amperometric enzyme electrodes have been reported that they have high sensitivity, selectivity, and long operational life and it is expected that the use of these for water analysis will become more widespread (see Table 8.2). For example, a sensitive enzyme electrode based on the amperometric detection of hydrogen peroxide produced by membrane coimmobilized nucleoside phosphorylase and xanthine oxidase has been reported for the detection of phosphate by D Urso and Coulet [123]. Other similar enzyme electrode systems suitable for water analysis are listed in Table 8.2.
