## Abstract The distribution equilibria of single and binary L‐phenylalanine and L‐aspartic acid between water and a kerosene solution of di(2‐ethylhexyl)phosphoric acid (D2EHPA) were studied. It was shown that the distribution ratios of phenylalanine generally increased with increasing aqueous pH
## Abstract BACKGROUND: Di‐(2‐ethylhexyl)phosphoric acid (D2EHPA, H~2~A~2~) has been used extensively in hydrometallurgy for the extraction of rare earths, but it has some limitations. Synergistic extraction has attracted much attention because of its enhanced extractabilities and selectivities. In
