SYNERGISTIC EFFECT OF Ni EXTRACTION AND ITS APPLICATION FOR WASTE SOLUTION IN Ni NON-ELECTRIC PLATING Yoshikawa, Norio Yajima, Masato 90340653 Murayama, Norihiro 30174808 Yamamoto, Hideki Shibata, Junji Waste solution from the Ni non-electric　plating process contains 4.0kg/㎥ Ni (II), 0.1kg/㎥ Fe (III), 0.01kg/㎥ Zn (II), 48kg/㎥ SO₄²⁻, 98kg/㎥ HP0₃²⁻ and 31kg/㎥ lactic acid as a typical composition. Solvent extraction, cementation, ion exchange resin and precipitation methods may be used for the treatment of this kind of solution. In this study, solvent extraction of Ni (II) is investigated using two kinds of extractant in order to clarify the relation between extraction percent age and pH for various extractant mixtures. As Ni ions have an octahedral structure with ligands, the synergistic effect for Ni extraction may be effected by using two types of extractants. 関西大学工学部 2004 eng departmental bulletin paper VoR http://hdl.handle.net/10112/5701 https://kansai-u.repo.nii.ac.jp/records/11766 AN00046916 04532198 関西大学工学研究報告 = Technology reports of the Kansai University 46 11 19 https://kansai-u.repo.nii.ac.jp/record/11766/files/KU-1100-20040000-02(1).pdf application/pdf 8.6 MB 2019-05-23
