The thermal stability of DIT was studied and was compared with that ofthe inorganic iodine KI. The results showed that DIT was still stable whilealmost all I- volatilized under the same treatment at 270OC for 2 hours.

• 本文研究了海带中生物活性碘DIT的热稳定性，并与无机碘剂KI的稳定性进行了比较，结果表明，270aC下加热处理2小时，DIT依然稳定地存在，而 厂几乎全部挥发。
