  • EXTRACTION EQUILIBRIA of HYPOPHOSPHOROUS, PHOSPHOROUS and PHOSPHORIC ACIDS by TOLUENE SOLUTION of TRI-N-OCTYLAMINE
    ARS SEPARATORIA AA ACTA Ars Separatoria Acta 2 (2003) 125-138 www.ars_separatoria.chem. uni.torun.pl EXTRACTION EQUILIBRIA OF HYPOPHOSPHOROUS, PHOSPHOROUS AND PHOSPHORIC ACIDS BY TOLUENE SOLUTION OF TRI-n-OCTYLAMINE Takashi SANA2, Koichiro SHIOMORI1, and Yoshinobu KAWANO1* 1 Department of Applied Chemistry, Miyazaki Univ., Miyazaki 889-2192, Japan e-mail: [email protected] 2 Yoshitama Surface Finishing Co., LTD, Nobeoka 882-0024, Japan ABSTRACT The extraction equilibria of hypophosphorous, phosphorous and phosphoric acids with tri-n-octylamine as an extractant in toluene were measured at 303K. Under these conditions, undissociated acid (A') reacts with the amine (B) to form various complexes in toluene. The complexes formed and equilibrium constants were estimated by a graphical analysis method. The complexes formed in these systems were found to be A'nB type species for hypophosphorous acid, A'nBm type species for phosphorous acid, (A'B)n type species for phosphoric acid, respectively. The experimental results could be explained by reaction models and equilibrium constants for each acid. Keywords: Hypophosphorous acid; Phosphorous acid; Phosphoric acid; Tri-n-octylamine; Extraction equilibrium INTRODUCTION Solvent extraction gives the advantage of selective separation in the recycling of useful materials [1,2]. The nonelectrolytic nickel-plating wastewater consists of nickel, some organic acids, hypophosphorous acid, phosphorous acid, and phosphoric acid. In order to design a new wastewater treatment equipment of nonelectrolytic nickel-plating, it is necessary to clarify the extraction equilibrium and kinetics for each component contained in wastewater. For that fundamental knowledge, the extraction equilibrium and kinetic for nickel with 5-dodecylsalicylaldoxime [3,4] as well as * Corresponding author 125 Sana, et.al.
