关于四苯卟啉(H_2TPP)及其第一过渡金属配合物(MTPP,M=Mn,FeCl,Co,Ni,Cu,Zn)对H~+通过W/NB界面所产生的推动作用前文已作报道。本文研究上述两者对Fe~(3+)在W/NB界面迁移的影响,并根据实验事实提出可能的微观机理。 实验仪器、电化学测试方法及主要试剂的制备、纯化参照前文。主要结果如下。H_2TPP对Fe~(3+)在W/NB界面迁移的影响

The Effects of Tetraphenylporphyrin and Its Metal Coordination Compounds on Assisting Fe~(3+) Ion Transfer Across the W/NB Interface

The roles of tetraphenylporphyrin(H2TPP) and its first transition-metal coordination compounds(MTPP,M==Mn,FeCl,Co,Ni,Cu,Zn) assisting Fe2+ ion transfer across the water (W)/nitrobenzene(NB) interface were investigated by using the measurement system of micro-com-puler. The experimental results showed that: (1)Under the condition of H2TPP concentration in NB phase being less than 0. 6 mmol/l, the process of Fe3+ ion transfer across the W/NB interface faclliat-ed by H2TPP was reversible. When y was more than 0. 6 mmol/1, the transfer process of Fe3+ ion was inhibited. The intcrlayer became inert; (2) Various MTPP showed certain active effect on Fe3+ ion transfer across the W/NB interface, yet the transfer process were irreversible. The corresponding micro-scopic transfer mechanisms were considered for above-mentioned processes.
