Description
Micro Water and Soil Nitrite Content Assay Kit provides a simple, convenient and rapid method for the determination of nitrite content, which is suitable for water and soil samples. The detection principle is that under acidic conditions, nitrite reacts with p-aminobenzene sulfonic acid to form diazo compounds, and then reacts with Nmuri 1-naphthyl ethylenediamine to form purplish red azo compounds with a characteristic absorption peak at 540 nm
