Making Iodine from Seaweed

There's one experiment (posted somewhere on this forum) involving burning seaweed to ash, boiling the ashes with water, filtering and collecting the filtrate, and adding to it a solution of acidified hydrogen peroxide. I've tried the lab many times with careful attention to precision, yet each time, I failed miserably. If anyone is familiar with the extraction process (or any other method for isolating iodine) and can lead me through it, that would be great. Thanks
