Which substance is NOT typically used for the removal of fluoride in water?

Activated alumina
Sodium hypochlorite
Reverse osmosis
Ionic exchange

The correct answer is: Sodium hypochlorite

Sodium hypochlorite is primarily used as a disinfectant for treating water, effective in the elimination of bacteria and viruses. While it plays a critical role in maintaining water quality, it is not utilized for the specific purpose of fluoride removal. In contrast, activated alumina, reverse osmosis, and ionic exchange are all effective methods for reducing fluoride concentrations in water. Activated alumina functions by adsorbing fluoride ions, while reverse osmosis uses a semi-permeable membrane to separate fluoride from the water. Ionic exchange involves exchanging fluoride ions with less harmful ions, effectively reducing fluoride levels. These methods are designed specifically to target and remove fluoride, showcasing the need for various approaches to handle different contaminants in water treatment processes.
