摘要:

A turbidimetric method was developed for the determination of 2–30 ppm nitrite after reacting with sultamic acid to produce sulfate which was coinverted to barium sulfate and measured turb idimetrically. Several diverse ions were found not to interfere. The interference by phosphate and sulfate was overcome by treating the sample with barium chloride prior to the addition of sulfamic acid and centrifuging.
