the first place to try is your local pharmacy, they can get the iodine chrystals for you. will they get them? who knows.
as far as the effectiveness of the iodine in decontam. of water, there has been some discussion over on the hoodlum site and you might want to check it out.
there has also been some discussion on the use of potassium permanganate for water decontamination.
thanks my pharmacy does have it! it is cheap too! 18oz. for 7.00 not bad.
I haven't gotten over to the hoodlum site yet, pretty busy down here.
I am thinking of retruning or selling my PUR water filter/purifier. it is too darn bulky and the filter has been known to get clogged.
I think the iodine would work great with clear water but dirty brackish water must be filtered. so I am thinking of using panty hose with charcoal as a filter.
I'll try to attach a photo of a design I pulled off the internet.
You can also carry a few paper coffee filters in your kit to strain debris & crud out of water. They weigh almost nothing. You would of course still need to decontaminate the water for chemicals or organisms.
iodine is an element, it cant expire, it will last forever, unless it reacts with something, or evaporates. so take it and run, or wait until it is ready to expire and give them a buck for it.
Ron, recommends a 1oz glass jar with 8 grams of iodine crystals.
I got an old lemon extracts jar. went to the pharmacy and had them measure out 8 grms for me. but in hind site on the hoods woods website there is a link to christopher nygeres(sp?) site where he sells the whole set up for 6.oo including shipping. so I would do that.
I pulled out the cardboard disk in the metal cap on the bottle. hopefully it won't leak?
this method seems like the best. I have been a pur purifier fan for a few years. the Iodine crystal method is more compact, light, cheaper and longer lasting. sounds great lets hope it works.
PolarPure uses iodine crystals in a solution. You add a capful of the solution to a liter or quart of water (or two, depending on temperature), then refill the bottle to recharge it. One small bottle is enough to treat 2,000 liters. It cost about $7 Canadian ($5 US). Great for traveling; just got back from Mexico where I used it to treat tap water in our hotel to fill our water bottles. The iodine taste isn't bad.
