The extraction of nitric acid from aqueous solution by tri-n-butyl phosphate has been investigated. From the volume changes it has been shown that up to ~3.8 Macid in the organic phase the extraction is due to the formation of Bu/sub 3/PO/sub 4/,HNO/sub 3/ by addition at the strongly polar P yields O group. When this donor oxygen is saturated, futher addition takes place at the less basic oxygen atom of a P-O-C bond; in this case, the acid is shown to be extracted as H/sub 2/O,HNO/sub 3/. The experimental results are discussed in relation to mass-action equations derived for these two types of equilibrium. (auth)
