摘　　要：本文用气泡式准乳化液膜法研究了对叔丁基杯芳烃及其衍生物对Fe3 + 离子的液膜传输作用 ,并对其传输规律、影响因素 (源相及吸收相的酸度 ,金属离子的浓度 ,传输载体类型等 )及传输机理作了初步探讨 .The liquid membrane transportation of Fe\+\{3+\} ion by p-tert-butylcalix[n] arene as carriers was investigated by the bubbling pseudo-emulsion liquid membrane.The driving force for transport is the pH gradient between the source phase and the receiving phase.The selective transport for Fe 3+ ion or Cu 2+ ion by p-tert-butylcalix[6] arene acid as carrier is investigated.Several serries of calix-arenes used as carriers for transport across liquid membrane are compared,and the transport mechanism is dircussed.
