Treatment of radioactive organic liquid waste containing TBP and dodecane; Tratamento de rejeitos radioativos compostos por solventes organicos: sistema TBP/dodecano

Technical Report:

Abstract

It was studied an alternative for the treatment of radioactive liquid wastes containing organic solvents, particularly spent TBP and its diluent dodecane. The proposed method is divided in two distinct steps: separation of TBP and dodecane by treating the organic solution with concentrate phosphoric acid and immobilization of separated TBP by incorporating it into PVC polymers. It was determined the operational conditions for both steps such as quantity of H sub(3)PO sub(4) necessary to form the adduct, PVC to TBP proportion, temperature of solidification, adequate type of PVC and others.
