Latest Patents
One of his latest patents is titled "Method and filter for removing nitrate ions." This invention presents a method for effectively removing nitrate ions from a solution. The process involves providing a polymer that contains a protonated amine moiety and an anion derived from an acid with a pKa value greater than about 1. The polymer is then contacted with the solution to bind a portion of the nitrate ions, forming a polymer-nitrate complex, which can be separated from the solution.
Another significant patent is "Polymer and method for using the same." This invention describes a polymer derived from the reaction of glycidyl (meth)acrylate, allyl glycidyl ether, or [(vinyloxy)methyl]oxirane with ammonia or a primary amine. The process continues with the reaction of the resulting mixture with various compounds to obtain an intermediate polymer, which is then reacted with a dithiocarbamic acid salt. The patent also outlines methods for utilizing this polymer.
