An ionic imprinted membrane (IIM) was synthesized using sulfonated polyeugenol, derived from eugenol, as its functional polymer and polysulfone as its base membrane for the selective adsorption of Au(III). This study aims to determine the adsorption of Au(III) metal ions using IIM compared with the non-imprinted membrane (NIM) and to figure out the membrane selectivity towards Au(III) in mixed solutions of Au/Cd, Au/Cu, and Au/Fe. IIM has a pore size of 0.767 μm while the non-imprinted membrane (NIM) has a pore size of 0.853 μm. The best adsorption result was obtained in the variation of the membrane with the addition of 3.84 g of polysulfone that had pores according to the size of Au. The selectivity results of the Au/Cd mixture solution in NIM and IIM were 17.802 and 36.265. In the mixture of Au/Cu, the NIM and IIM selectivity was 2.386 and 6.886, and in the mixed solution of Au/Fe, the selectivity of NIM and IIM was 0 and 8.489. Thus, the selectivity of IIM towards Au is bigger than NIM.
以丁香酚衍生的磺化聚丁香酚为功能聚合物，聚砜为基膜，合成了一种离子印迹膜（IIM），用于选择性吸附Au(III)。本研究旨在确定使用IIM与非印迹膜（NIM）相比对Au(III)金属离子的吸附情况，并弄清楚该膜在Au/Cd、Au/Cu和Au/Fe混合溶液中对Au(III)的选择性。IIM的孔径为0.767μm，而非印迹膜（NIM）的孔径为0.853μm。在添加了3.84g具有根据Au尺寸的孔的聚砜的膜变体中获得了最佳吸附结果。NIM和IIM中Au/Cd混合溶液的选择性结果分别为17.802和36.265。在Au/Cu混合物中，NIM和IIM的选择性分别为2.386和6.886，在Au/Fe混合溶液中，NIM和IIM的选择性分别为0和8.489。因此，IIM对Au的选择性大于NIM。
