3. Applications :

A. Agriculturally, iodine is the material for pesticide.

Vegetables, fruits and crops sprayed with iodine solution (1 of 20000) can be prevented from worm-eaten, can grow rapidly with higher yield.

Silver iodide is used as the atomizing agent in artificial rain.

B. In dyestuff industry, iodine is the material to synthesize organic dyestuffs.

C. In lighting industry, tungsten-iodine lamps made from iodine give strong light. Indium iodide and thallium iodide are used to make colorful light lamps.

D. In food industry, sodium iodate can improve the quality of bread, potassium iodate can be additive in salt. Iodalbin added in feedstuffs can prevent against various diseases.

E. Iodine is used in chemical industry as catalyzer, in chemical synthesizing industry, used to synthesize methane iodide, ethane iodide; In metallurgical industry, iodine is used to refine high purity mental titanium, cobalt, silicon and germanium.
