Title: Wilhelm Ochsenfeld: Innovator in Waste Minimization and Plutonium Stripping

Introduction

Wilhelm Ochsenfeld is a notable inventor based in Karlsruhe, Germany. He has made significant contributions to the fields of waste management and nuclear reprocessing through his innovative patents. With a total of two patents to his name, his work focuses on minimizing organic waste and efficiently extracting plutonium.

Latest Patents

Ochsenfeld's latest patents include a method for minimizing organic waste in aqueous product streams. This method addresses the challenge of treating aqueous process streams that contain small quantities of interfering substances, such as organic extraction agents and their decomposition products. The solution involves using a macroporous sorption resin based on polystyrene cross-linked with divinyl benzene, which selectively sorbs the interfering substances. The resin can be regenerated using a regenerating solvent, allowing for the recovery of pure solvent and the recirculation of the extraction agent.

Another significant patent by Ochsenfeld is a method for stripping plutonium from tributyl phosphate solutions. This process is crucial for reprocessing highly burnt-up fast breeder fuel elements. The method involves extracting uranium and plutonium into an organic solution containing tributyl phosphate, which partially degenerates into dibutyl and monobutyl phosphates. These compounds form stable complexes with tetravalent plutonium, which can then be stripped into an aqueous phase by contacting the organic solution with an aqueous phase containing tetravalent uranium.
