Quantitative analysis of some extractants by infrared spectrometry
- 37 Downloads
A method is described for the estimation by infrared spectrometry of some organic extractants such as tributyl phosphate (TBP), dioctyl sulfoxide (DOSO) and dibutyl decanamide (DBDA), which have importance as solvent extractants for fuel reprocessing. Measurements have been carried out using their characteristic donor peaks. Results indicate that Beer's law is obeyed in the concentration range of 0.01 to 0.2M with an optimum around 0.1M. The estimations have also been carried out by measuring the intensities of the OH stretches of the donor hydrates, which are very useful in estimating these donors in solvent extracted species. The method has been successfully applied to the determination of amide contents of irradiated dialkylamides.
