The use of 100% diphenyl(dibutylcarbamoylmethyl)phosphine oxide in the extraction of metals from nitric acid solutions
Abstract
A change in the physical state of diphenyl(dibutylcarbamoylmethyl)phosphine oxide (DϕDBCMPO) upon contact with an acidic solution is described and the composition of the complex formed by the reagent and the acid is established. The quantitative characteristics of the extraction capacity of this complex are found using praseodymium as an example, and the advantages of using 100% DϕDBCMPO are shown.
