Abstract
This invention provides a method to recover valuable DTPA from DTPA solvent extraction organic solution that avoids the need to operate at either high or very low temperatures, with extended reaction times and having to carry out solid/liquid separation on organic solution. Furthermore, the invention provides the flexibility of selecting appropriate base solution to carry out the DTPA recovery process and further provides the ability to directly treat metal-containing DTPA organic solution.
