Patent teaches the removal of plutonium from water

Gary Silver of Centerville, Ohio was the inventor of a now expired patent for the removal of plutonium from water. The patent utilized chitin to remove the majority of plutonium in a solution of water. Water is buffered to between 5 and 10 and chitin is added to absorb the plutonium followed by the removal of the plutonium laden chitin from the water and eventually the incineration of the chitin to yield a plutonium rich ash.

The plutonium removal process was granted United States Patent 4,120,933 entitled “Decontamination of plutonium from water with chitin.”  A process such as this could be put to use in an attempt to control the amount of radioactive materials in the water that is escaping from the Japanese reactors.  However, this is not the type of solution that could be used to completely remove radioactive materials from the contaminated water.
