摘要：

The stability of optochemical nitrate sensors based on immobilized pH indicators in hydrophobic membranes was investigated. The chemical structure of the pH indicator (i.e., chromoionophore) was found to affect the stability as well as the pH-operation range of the sensor. Different matrices were tested for the immobilization of the sensing compounds, and the influence of continuous sensor operation on its properties was proofed.
