A new flow injection enzymatic biosensor was designed for selective determination of phosphate ions. Pyruvate oxidase (PyOX) and multiwall cabon nanotubes (MWCNTs) were immobilized on the surface of a glassy carbon electrode by the nafion polymeric layer. The measurement method was based on fast Fou...
