以三异辛胺为载体的乳状液膜迁移、分离汞(Ⅱ)的研究

Study on the Transport of Hg(Ⅱ) Ions Through a Tri iso octylamine (TIOA) Sorbital Monodeate (Span80)-Toluence Liquid Membrane

研究了用Ｓｐａｎ８０—三异辛胺—二甲苯乳状液膜体系迁移汞（Ⅱ）的行为及机理，确定了合适的迁移条件，并能使汞（Ⅱ）与常见离子得到分离．

A study of the transport of Hg(Ⅱ) ions through a tri iso octylamine(TIOA) sorbital monooleate (Span80) toluence liquid membrane has been performed and the proper conditions of the transport of Hg(Ⅱ) were selected. With this system, Mercury could be corupletely separated from Cu,Zn,Fe, Co, Ni,Mn, Cd, Cr, Al and Pb. The transport mechanism of Hg(Ⅱ) has also been discussed.
