- Interference of High Degrees Salt on Spectrophotometric Flow Injection Analysis : Quantitative Error of Nitrite from Schlieren Effect and Salt Effect
Search this article
Abstract
Interference of high salt concentrations in spectrophotometric flow injection analysis is described. The spectrophotometric determination of nitrite with Griess reagent was used as a test model. Several percentage concentrations of sodium chloride, magnesium chloride, or magnesium sulfate solutions caused more than 10% positive interference in determining 0.040 mg L-1 nitrite. This interference was attributed not only to the schlieren effect but to the salt effect, i.e., the accelerated reaction of nitrite with the Griess reagent.
