di-(2-ethylhexyl) phosphoric acid

The solvent extraction of cerium(III) from its sulfuric solution with di-(2-ethylhexyl) phosphoric acid diluted by kerosene was investigated. Initially, a survey was conducted in order to identify the conditions influencing the solvent extraction process. Extractant concentration in the organic phase, organic phase to aqueous phase ratio, temperature, pH, and contact time were identified as important factors. Among these factors, the temperature and contact time were found less effective in comparison to other factors.
