摘要: ABSTRACT The extraction of Ni(II) from 1.0 mol-dm-3aqueous NaNO3medium by di-(2-ethylhexyl) phosphoric acid (HDEHP) dissolved in toluene has been studieo as a function the total extractant concentration, equilibrium pH and raetal concentration aqueous phase. Nickel distribution data have interpreted terms formation NiR2(HR)2, NiR2species organic phase low range anc Na-HUEHP micelles, due to neutralization reagent phase, further exchange Na+by Ni2+in these micelles high for each concentrations used.
