ABSTRACT:
A method for detecting the presence of nitrite ions in fluids by pretreat nitrite containing fluids to enhance the detectability with nitrite detecting reagents of the nitrite ions therein, which pretreatment step comprises passing the nitrite containing fluids through activated charcoal prior to combination with a nitrite detection reagent.
Also a test kit for carrying out the above method.
