Iodine was banned in a 2009 or thereabouts European directive as a chemical for purifying drinking water.
A quick and pretty reliable water purification method is Potassium permanganate (KMnO4) aka Condy's crystals. You only need a 3 or crystals per liter (until it starts to turn pink), and let sit for 30 minutes.
In stronger doses, it's also a great antiseptic.
Don't overdo it on the drinking water unless you want your teeth to turn brown!
