METHOD TO ANALYZE NITRITE CONTENT IN CHEMICAL CLEANING FLUID
The method to determine nitrite content in chemical cleaning fluid was set up by experiments. Based on the characteristic of nitrite, the direct titration and indirect titration method in redox titration were selected, the diluted sample was examined by spectrophotometry, and the nitrite was used as the primary reagent to verify the method to select which one was the most suitable.
