CHLORAMINE

• A combination of chlorine and ammonia is now widely used for the sterilization of water.
• It is less affected by the presence of organic matter and its sterilizing action is more prolonged than that of chlorine.
• Its only advantage over chlorine is that it does not to the same extent give raise to iodoform and chlorinous tastes in the water.
• Its bactericidal effect is however, very much slower than that of chlorine and long contact is therefore necessary which in many circumstances is a decided drawback to the use of chloramine.
