Title: Takayuki Morioka: Patents in Water Treatment and Radioactive Resin Processing.
Introduction
Takayuki Morioka is an inventor associated with Kawasaki, Japan, and Fuji Electric Co., Ltd. His patent work includes technologies for ozone-based water treatment and the oxidative decomposition of radioactive ion-exchange resins. The supplied information lists 2 patents.
Latest Patents
Morioka’s listed patents address two distinct treatment challenges.
“Water Treatment Process with Ozone” describes a process for oxidizing and decomposing trace organic substances in water. Ozone is diffused into water in a reaction tank, while a chelate compound is added to the water after or shortly before it enters the tank. Preferred compounds include several salts of ethylenediaminetetraacetic acid, as well as iron citrate.
“Method of Treating Radioactive Ion-Exchange Resins by Oxidative” concerns the oxidative decomposition of radioactive resin containing an anion-exchange resin. The method uses hydrogen peroxide as an oxidizing agent and iron and copper ions as catalysts. It specifies limits for the hydrogen-peroxide-to-resin weight ratio and a reaction-system pH range of 0.5 to 6. It also describes using citric acid ions, either adsorbed onto the resin beforehand or present during decomposition, and includes an apparatus for carrying out the method.
Career Highlights
The listed inventions reflect work on treatment processes involving chemical oxidation. One focuses on removing trace organic substances from water, while the other addresses the processing of radioactive ion-exchange resins. Both patents describe methods intended to control treatment conditions and chemical inputs.
Collaborations
Morioka’s listed coworkers include Nobuyuki Motoyama and Tuyoshi Ishikawa. The supplied information associates his work with Fuji Electric Co., Ltd.
Conclusion
Takayuki Morioka’s listed patents cover ozone-assisted water treatment and the oxidative decomposition of radioactive ion-exchange resins, highlighting two applications of chemical treatment technology.
