Description

Scope and application of the reagent Monochlor F (2802299)

  • For monitoring free ammonia levels during chloramines production, at pumping / compressor stations and in drinking water distribution networks.
  • For the determination of residual levels of free chlorine in the presence of manganese, chloramines and other oxidants that interfere with colorimetric, titrimetric and amperometric methods in the determination of free chlorine by the DPD method. For use in drinking water, chlorinated drinking water and swimming pool water.
  • For chlorinated drinking water and chlorinated waste water.
  • For the simultaneous determination of free ammonia and monochloramine in finished water.

General description of the method

Monochloramine (NH2Cl) and free ammonia (NH3 and NH4+) can be present in the same water sample. The added hypochlorite combines with the free ammonia to form more monochloramine. In the presence of a cyanoferrate catalyst, monochloramine in the sample reacts with substituted phenol to form an intermediate monoimine compound. The intermediate combines with excess substituted phenol to form green indophenol, which is proportional to the amount of monochloramine present in the sample. Free ammonia is determined by comparing the color intensity with and without added hypochlorite. The measurement wavelength is 655 nm for spectrophotometers or 610 nm for colorimeters.
