Waste site reclamation with recovery of radionuclides and metals

摘要

A method for decontaminating radionuclides and other toxic metal-contaminated soil, sediment, sludge and aquatic milieus involves treating the contaminated material with a hydroxycarboxylic complexing agent in a solution. The treatment solution is then treated with a Pseudomonas fluorescens ATCC No. 55241 and subjected to photolysis to degrade the complex and recover the radionuclides and metals in a concentrated form through precipitation or incorporation into biomass.
