Latest Patents
Frederic holds a patent for a process aimed at purifying phosphoric acid for electrical semiconductor use. This patent involves treating phosphoric acid to remove and/or tie up heavy metals and antimony. The process includes reacting the acid with hydrogen sulfide and hydrogen peroxide in separate treating steps. The hydrogen sulfide precipitates metal sulfides, which are then separated from the acid. Meanwhile, the hydrogen peroxide oxidizes dissolved antimony, ensuring it is tied up and does not post-precipitate in the acid after the removal of the metal sulfides. Frederic has 1 patent to his name.
