The study on solvent extraction of nickel(II) from sulfuric acid solutions with 2-ethylhexyl 2-ethylhexyl phosphonic acid (PC88A) has been studies. The influence of various factors such as concentrations of PC88A, sulfuric acid, pH and nickel(II) on the distribution coefficient has been studied. It was found that the recovery of nickel up to 99.72 percent from Ban Phuc, Son La ore nickel by using 2-ethylhexyl 2-ethylhexyl phosphonic acid should be carried out under the following conditions at pH 6 extracts washed 3 times with H2SO4 5 M.
