Radioactive water: Tea Bags to the Rescue
Water is life for all of us and if this life giving becomes impure or not safe for drinking then it will pose a serious health hazard to all human beings and animals too.
Mostly we use chlorine tablets, boiling technique, and Reverse Osmosis method to purify water. But what we will do if the water contains radioactive materials in it. They cannot be removed by these above discussed ways, so for that we need some other technique through which we can make water safe for drinking.
There are multiple organisms that are in the water, different minerals that we don’t want in abundance of. We count on our tap water to be clean and safe to drink. But contamination is a continuing concern. It is definitely an environmental issue. Radioactive substances can be removed from the drinking water by the use of biodegradable foam.
It works like a goeey sponge to pull salt, heavy metals, and even radioactive materials like potassium iodide that don’t dissolve out of water. And it can also work for a lot of the other ions that are created from nuclear reactions.
This biodegradable foam is made from combination of hemicellulose (a by – product of the wood pulp industry) and chitosan that is typically found in crushed crustacean or crab shells. The materials can be used to remove contaminants.
This materials itself is not selective for radioactive materials, but it is used to remove dissolved, ions in water.
In a disaster, it could be as simple to use a tea bag, for that take a cup of water, place your tea bag into the water and it will remove the salt, heavy metals and hopefully radioactivity from the water.
One litre of foam can turn a 100 litres of contaminated water into safe drinking water.
