Abstract
Processes for extracting iodine from an aqueous solution, such as brine, are disclosed. Activated coconut carbon particles are mixed with the solution to adsorb iodide through pores in the activated carbon particles. The activated carbon particles are then treated with sulfur dioxide gas and water to form hydrogen iodide. The hydrogen iodide is then reacted with chloride to obtain elemental iodine (I).
