摘要：

A bienzymatie sensor for the determination of phosphate was constructed by coimmobilization of xanthine oxidase (EC 1.2.3.22) and nucleoside phosphorylase (EC 2.4.2.1) on a polycarbonate membrane mounted on the tips of amperometric hydrogen peroxide and oxygen electrodes. The sensor response was linear to phosphate concentrations in the range 10-250 μm. © 1990.
