The phosphate sensor.
The field of phosphate sensors is reviewed. Sensors in the form of potentiometric ion-selective electrodes, amperometric and potentiometric enzyme electrodes, amperometric plant-tissue electrodes and other devices in the form of integrated probes used for determining orthophosphate concentrations in aqueous solutions, are described. Information provided includes conditions like pH and temperature at which the device is operated, as well as experimental results in the form of linear ranges, detection limits and interfering substances. The time period covered ranges from 1986 up to mid-1997. Earlier work is included in some cases.
