Abstract
PURPOSE: To provide a solvent extracting reagent with increased chromic acid ion extracting speed by adding trialkylamine or dialkyamine to trialkyphosphoric acid.
CONSTITUTION: To 1mol trialkylphosphoric acid represented by formula (RO)3 P=O (where R is 4W24, preferably 4W12C alkyl) is added 0.1W7mol alkylamine represented by formula R3'N and/or R2'NH (where R' is 8W24, preferably 8W18C alkyl). The molar ratio of the alkyamine to the acid is preferably 0.2W2. A remarkable effect is produced especially when tributylphosphoric aicd and/or trioctylphosphoric acid and trioctylamine and/or dioctylamine are used in the above- metioned molar ratio.
