Özet
The present study is on the reactive extraction of picric acid (HPc, 2,4,6-trinitrophenol) from dilute aqueous solutions by organic phases containing Amberlite LA-2 (ALA 2) as extractant dissolved in four types of ketones. The studies were performed at 298, 308, and 318 K, and the results were used to calculate the values of distribution coefficient (KD), loading factor (Z), and degree of extraction (E%). Initial HPc concentration was kept constant at 0.061 mol.kg(-1). The maximum KD was obtained as 60 using methyl ethyl ketone when initial concentrations of PA and ALA-2 were 0.061 and 0.59 mol.kg(-1), respectively. The extraction efficiency was 98.36% under these conditions. Moreover, z-values between 0.09 and 0.27 were obtained in the ranges of parameters studied. Calculated values show that 1:2 picric acid-ALA-2 complex dominates the extraction process.
