Experimental Study of the Waste Gas of COIL Removing Iodine

Chemical oxygen-iodine laser (COIL) has wide application prospects in the fields of national defense and industry, but at the same time COIL discharges out a large of corrosive gas, especially the iodine crystal of the waste gas endangers the equipment and environment gravely. Firstly the quantitative test on utilizing the iodine adsorption vessel to remove the methyl iodine by the soaked coal-based active carbon was did , then the qualitative test of the coal-based active carbon for removing stable iodine on the base of the first test was carried on. The result of the test indicates that the decontamination factors of the coal-based active carbon for removing the stable iodine is more than 1000, so it can satisfy the need of project application, and it is very important to deal with the waste gas of COIL and other nuclear facilities.
