Element for the determination of nitrate
- Patent Nr: 2259541
- Concession Date: 29.08.2007
- Abstract: the element is based in the use of synthetic receptors for nitrate, and the optic signal lis obtained by coupling in the hydrophobic sensor membrane an lipotilized acid-base indicator. The measure or observation of a color change from red to blue depending on the amount of nitrate in the problem allows its determination in a wide range of concentrations with high accuracy and selectivity for concomitant anions with nitrate. The present invention can be alternative con advantages such as quickness, precision and cost over other analytical methods, and over the commercial reactive strips widely used in water analysis and agriculture.
