摘要
A method for determining orthophosphate content of a liquid, comprising: registering a first measurement signal (ISE1) of an ion selective dihydrogen phosphate sensor; registering a second measurement signal (ISE2) of an ion selective hydrogen phosphate sensor; and determining the orthophosphate content of the liquid based on the first (ISE1) and second (ISE2) measurement signals. The dihydrogen phosphate sensor can comprise an ion selective dihydrogen phosphate electrode and the hydrogen phosphate sensor an ion selective hydrogen phosphate electrode. In the step of determining the orthophosphate content of the liquid, a cross-sensitivity of the dihydrogen phosphate electrode to hydrogen phosphate present in the liquid and a cross-sensitivity of the hydrogen phosphate electrode to dihydrogen phosphate present in the liquid can be taken into consideration.
