Overview
Cadmium iodide is an iodide of cadmium that can be made by heating cadmium with iodine. It is used in lithography, photography, electroplating and the manufacturing of phosphors. Cadmium is a transition metal and chemical element with the symbol Cd and atomic number 48. It is found naturally in the earth's crust, though rarely on it's own. (L6, L469)

Safety & protection
Exposure Control and Personal Protection
Biological Exposure Indices (BEI) [ACGIH] - Cd in urine = 5 ug/g creatinine; Cd in blood = 5 ug/L; sampling time not critical; Monitoring in blood should be preferred during the initial year of exposure and whenever changes in the degree of exposure are suspected. [ACGIH]
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Cadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (L6)

Applications
DescriptionCadmium iodide (chemical formula: CdI2) is a chemical compound consisting of cadmium and iodine element. It appears as a green-yellow solid, being soluble in water, alcohol, ether, acetone, ammonia, and acid. It is a compound with the typical crystal structure of the form MX2, exhibiting strong polarization effects. It has many applications such as being used in lithography, photography, electroplating, process engraving, analytical chemistry, electrodeposition of cadium as well as the manufacturing of phosphor and lubricants. It is manufactured through the reaction between cadmium metal, or its oxide, hydroxide or carbonate and hydroiodic acid.
UsesCadmium iodide is used in lithography, photography, electroplating and the manufacturing of phosphors, in engraving process, and was used as an antiseptic and astringent.
