Documented Uses

• Used as a humidity indicator and catalyst; [Merck Index]
• Cobalt(II) iodide is used to detect the presence of water. (L33)
• Cobalt is absorbed though the lungs, gastrointestinal tract, and skin. Since it is a component of the vitamin B12 (cyanocobalamin), it is distributed to most tissues of the body. It is transported in the blood, often bound to albumin, with the highest levels being found in the liver and kidney. Cobalt is excreted mainly in the urine and faeces. (L29)
