摘要
A study of the transport of Hg? ions through a hexadecylamine(RNH2)-sorbital monooleate (Span80)-kerosene liquid membrane was performed with varying concentration of HCl,KCl,Hexadecylamin,Span80 and NaOH in the feed,membrane and stripping solutions.Maximum transport was observed at (001～010)mol/L HCl,0020mol/LKCl,(0020～0030)mol/L RNH2,3%(w/v) Span80 and (001～002)mol/L NaOH.With this system,mercury could be completely separated from Fe2+,Co2+,Ni2+,Mn2+,Zn2+,Cu2+,Al3+,Cd2+,and Pb2+.The transport mechanism of these metal ions through the membrane was also discussed.
