Which of the following is true about chloramine?

Chloramine is a compound commonly used in water treatment as a disinfectant. It is particularly valued for its ability to maintain residual disinfection in water systems over a longer period than free chlorine. This characteristic makes chloramine an effective choice for controlling bacterial growth in the water distribution system.

Regarding the statement that chloramine must be removed for dialysis, this is accurate. Patients undergoing dialysis are sensitive to chloramine because it can react with the components of the dialysis equipment and potentially harm patients. Therefore, it is crucial to remove chloramine from water used in dialysis procedures to ensure patient safety.

The other statements regarding chloramine do not hold true. For example, chloramine is more stable than free chlorine, which contributes to its extended effectiveness as a residual disinfectant in water systems. While it is true that chloramine is considered a less effective disinfectant compared to free chlorine for certain pathogens, particularly at lower concentrations, it is not accurate to say it is a poorer disinfectant overall since its stability and longevity provide significant advantages in water treatment applications. Additionally, chloramine does not evaporate quickly; it is less volatile than chlorine, which means it remains in the water system for a longer duration and does not dissipate as rapidly.

Thus, the necessity
