摘要: Abstract The distribution equilibria of Eu3+ between aqueous phases containing lactic acid and N' -(2hydroxyethyl)ethylenediamine-N, N, -triacetic (HEDTA) or diethylenetriamine-N, N', N'' -penetaacetic (DTPA) at constant ionic strength (μ = 1.0), n-dodecane solutions HDEHP have been studied. formation constants the simple Eu-lactate complexes Eu-lactate-HEDTA mixed complex were evaluated from K d data. conclusion is reached that no coextracted into organic phase tracer metal concentrations. separation factors Eu3+, Pm3+, Am3+ in presence HEDTA.
