Development of a simple method for the determination of nitrite and nitrate in groundwater by high-resolution continuum source electrothermal molecular absorption spectrometry

A simple method was developed for the determination of nitrite and nitrate in groundwater based on difference of thermal stability of the species in a graphite furnace and detection by high-resolution continuum source molecular absorption spectrometry of NO. •A simple method was developed for the de...
