Title: Innovations by Parameshwaran S Sundar

Introduction

Parameshwaran S Sundar is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of uranium extraction, holding a total of 4 patents. His work focuses on improving the efficiency and effectiveness of uranium extraction processes.

Latest Patents

One of his latest patents is titled "Reduction of iron precipitation in uranium extraction process." This invention addresses the issue of iron complex precipitation during the stripping of uranium with ferrous ion. The process involves oxidizing uranium with nitric acid and extracting it with an organic solvent. The innovation lies in pre-stripping with sufficient ferrous ion to reduce nitrates and nitrites formed during the oxidation, while ensuring that the amount of ferrous ion used does not precipitate uranium.

Another significant patent is the "Sulfide precipitation method of separating uranium from group II and III metal ions." This method allows for the separation of uranium from analytical Group II and Group III metal ions in an aqueous liquor containing uranyl ions. The process utilizes a non-interfering, water-immiscible organic solvent that reacts with uranyl ions to form a soluble complex. The method further involves washing the solvent with water if the liquor is acidic and adding an aqueous solution containing ammonium ions and sulfide ions to precipitate the metal ions as sulfides.
