Metal ion selective polymer inclusion membrane (PIM) was prepared by using cellulose triacetate as matrix, surfactin (SF) as ion carrier, and 2‐nitrophenyl n ‐octyl ether as plasticizer. The structure and morphology of the prepared PIM were characterized by means of thermogravimetric analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy. The effects of plasticizer and the amount of SF to ionic membrane flux were investigated, and the optimized component was obtained thereof. The selectivity of the membrane toward metal cation was studied and the order of Ni(II) > Ca(II) > Co(II) > Pb(II) > Cu(II) > Mg(II) was followed. In addition, the durability of the PIM was studied by successive reuse of the membrane, and the ionic flux slightly decreased after five cycles of reuse, indicating the excellent durability of the PIM.
