Title: Heiichiro Obanawa: Innovator in Uranium Isotope Separation

Introduction

Heiichiro Obanawa is a notable inventor based in Kamakura, Japan. He has made significant contributions to the field of chemistry, particularly in the area of uranium isotope separation. With a total of 3 patents to his name, Obanawa's work has implications for both industrial applications and scientific research.

Latest Patents

Obanawa's latest patents include a groundbreaking process for separating uranium isotopes by oxidation-reduction. This innovative method allows for the continuous separation of uranium isotopes, specifically .sup.235 U and .sup.238 U, using a column of an anion exchanger. The process not only separates the isotopes but also regenerates the oxidizing and reducing agents that become deactivated during the separation. This dual functionality is achieved by passing an eluate containing the deactivated agents through the column, thereby forming an oxidizing agent zone and facilitating the reduction of uranium.

Another significant patent involves a composite porous material that combines a particulate inorganic porous material with an organic resin containing micro-voids. This composite material boasts a surface area larger than that of the inorganic component, providing high dimensional stability and exceptional separating and adsorbing capacity. It serves as an effective adsorbent for various compounds and ions, as well as a packing material for gas or liquid chromatography.
