PNNL Researcher Dr. Gregg Lumetta Recognized with Chemical Separations Award

Additionally, he investigated leaching of aluminum from the sludge with sodium hydroxide as a front-end process to TRUEX. This leaching method was subsequently incorporated into the flowsheet currently planned for the Pretreatment Facility at the Hanford Tank Waste Treatment and Immobilization Plant.

Other accomplishments include the development of new ligands for cleanup, application of existing ligands for plutonium separation, and development of new methods for separating minor actinides such as americium and curium from dissolved irradiated fuel.

Lumetta is the sixth PNNL staff member to receive the award. He was honored at the annual Actinide Separations Conference in Salt Lake City in May.
