ABSTRACT
NITRATE DETERMINATION IN PLANT TISSUE WITH SPECIFIC ION ELECTRODE

Rafael Ruiz S.¹ y Luis Roldán U.²

Nitrate concentration determination with a specific ion electrode showed chloride interference at low nitrate (1 to 5 ppm) and high chloride (over 1%) concentrations interference was eliminated by the use of Ag resin, and the use of bidistilled water eliminated reading doift.
