| Abstract: | The content of iodine in table salt,always get lots of attention from public.And there are several different ways to analyze it.In this article,we look deeply into the visible spectrophotometry(starch must be used) method.Through a lot of experiments,the proper measure conditions have been found.We use this method to measure some table salt in the market.Further more,recovery test has been done to find out whether our method is right or wrong.The result is satisfying. |
