Stripping experiments were similar to the extraction, where the organic phase was iron-loaded D2EHPA, and the aqueous phase was the stripping agent oxalic acid.

WebPour the mixture to be separated into the separatory funnel using a funnel. Add the extracting solvent and stopper the funnel. Two layers should now be in evidence. Be sure you know which layer is which. Ordinarily, one layer is aqueous (polar) and one is organic (non-polar), with the organic layer being less dense and thus the top layer.
