The potentiometric determination of nitrate and chloride in plant tissue
Abstract
Several extracting solutions were evaluated for their
effectiveness in determining NO3- potentiometrically
with a selective nitrate ion electrode, and the results were
compared with a standard phenoldisulfonic acid method.
The nitrate electrode proved to be highly satisfactory for
determining NO3- in plant tissue, and is apparently
as accurate as the phenoldisulfonic acid method when Al2(SO4)3
+10 mg per ml NO3-N is the extracting
solution.
