Abstract

Di(2-ethylhexyl)phosphoric acid was used as the extraction agent for the extraction of o-aminophenol in 2-octanol and kerosene.Equilibrium data for active and inactive diluents were obtained at various di(2-ethylhexyl)phosphoric acid concentrations,the initial pH and carbinol(ethanol)of solution.The result indicate that the initial pH(pHin)values have a large effect on D values,at the same the concentration extractabilities of di(2-ethylhexyl)phosphoric increase as the polarity of diluted rise,The effect of extraction decrease largerly because of carbinol(ethanol).The experiment proved that it can process effective pretreatment on industry waste water.
