Abstract This paper improved the experiment of extraction and verification of iodine in kelp:soaking kelp ash in distilled water at normal temperature, making pressure filtration by plastic bottle, using cotton bud, spot plate and waste eyedrop bottle to do microscale experiment, and recycling the obtained organic solution of iodine by means of reverse extraction. It realized chemistry experiment of homely, green and microscale.
