Potentiometric determination of total nitrogen in soils by flow injection analysis with a gas-diffusion unit
A flow injection analysis (FIA) system incorporating a gas-diffusion unit and a potentiometric detector was developed for the determination of total nitrogen in soil digests. The solutions obtained from the Kjeldahl digestion of the soil samples were injected in the FIA system where ammonium was con...
