The release process and influencing factors of bioactive iodine of kelp are systemically studied by leaching experiment. The results showed that the bioactive iodine of kelp can be released rapidly and the principal form of iodine in lixivium is I- . There is a dynamic process between the release and absorption of iodine. With the increase of leaching water, the gross amounts of released iodine rise.There also exists a transforming process among I- , IO3- and organic iodine in lixivium.
