Halogenated aromatics are not considered interferences in the cyanide determination process. This determination typically measures the concentration of cyanide in water using methods like distillation followed by colorimetric or titrimetric analysis. While various substances can interfere with these methods, halogenated aromatics do not typically react or interfere with cyanide detection.

Conversely, ammonia and nitrites can influence the cyanide determination process because they may react with the reagents used or contribute to color generation, leading to inaccurate results. Chlorinated compounds might also interfere due to similar reactive properties in the presence of the assay reagents. Understanding these interactions is crucial in ensuring accurate quantification of cyanide levels in environmental samples.
