Which of the following is recognized as the most powerful disinfectant?

• A. Monochloramine
• B. Chlorine
• C. Dichloramine
• D. Trichloramine

Answer: (B)

Chlorine is recognized as the most powerful disinfectant among the options listed. Its effectiveness in killing a wide range of pathogens, including bacteria, viruses, and protozoa, makes it a preferred choice in water treatment processes. Chlorine works by penetrating the cell walls of microorganisms, leading to their destruction through oxidative processes. Additionally, chlorine remains active for a longer duration in water compared to other disinfectants, which contributes to its ability to provide residual disinfection in distribution systems. This residual effect ensures that the water remains free from contamination even after treatment, providing ongoing protection against microbial growth. While other options like monochloramine, dichloramine, and trichloramine serve as disinfectants as well, they typically offer less potency compared to chlorine. Monochloramine is often used as a secondary disinfectant due to its lower reactivity and longer-lasting residual effects, particularly in systems where the formation of harmful byproducts is a concern. However, in terms of sheer disinfectant power, chlorine stands out as the most effective option available.
