TI(Ⅲ)与V(Ⅴ)、Ti(Ⅳ)、Rh(Ⅲ)和Ir(Ⅳ)的析相绿色萃取分离

Green Extraction Separation of TI(Ⅲ) from V(Ⅴ),Ti(Ⅳ),Rh(Ⅲ) and Ir(Ⅳ) by Phase Separation

    摘要
  • 摘要: 在NaCl存在下,丙醇水溶液能分成醇/水两相,在分相过程中,TICl4-与罗丹明B(RhB)生成的TICl4-RhB+能被丙醇相完全萃取.当溶液中NaCl、丙醇和罗丹明B的浓度分别为170 g/L、30%(v/v)和0.28 g/L时,TI(Ⅲ)的萃取率达到97.9%以上,V(Ⅴ)、Ti(Ⅳ)、Rh(Ⅲ)和Ir(Ⅳ)基本不萃取,实现了TI(Ⅲ)与上述金属离子的分离.对合成水样中铊的分离和测定,效果良好.

     

    Abstract: The results showed that the n-propanol aqueous solution could be well divided into two phases with the action of NaCl. The associated ［TICl-4］［RhB+］formed with TICl-4  and Rhodamine B (RhB)could be completely extracted during this process. TI(Ⅲ) could be quantiatively separated from V(Ⅴ), Ti(Ⅳ), Rh(Ⅲ) and Ir(Ⅳ) by extraction，and values of extraction percentage of TI(Ⅲ) over 97.9%. when the concentrations of NaCl, n-propanol and Rhodamine B in solution are 0.17 g/L、30%（v/v）and 0.28 g/L, respectively. determination of Thallium in synthetic water sample with satisfactory results
