IIM Au(III) is a membrane with an Au(III) ion template. This study aimed to determine the pH effect of a feed phase for selective transport of IIM Au(III), comparing it with a non-imprinted membrane (NIM) against Au 3+ metal ions from motherboard waste. It also aimed to compare the membrane selectivity of Au 3+ metal ions to Cu 2+ metal ions, which are also found in motherboard waste. Gold samples were prepared using H(AuCl 4 ) standard and leaching solutions from motherboard waste. The leaching of the motherboard used aqua regia and the assistance of a microwave to accelerate the leaching process. The optimum transport of Au 3+ metal ions was when using IIM Au(III) at pH 3. This proved that the presence of a template affected IIM Au(III) to recognize Au(III) ions. IIM Au(III) showed higher selectivity than NIM, as evidenced by the percentage in the receiving phase of the Au 3+ metal ions, which was more significant than the Cu 2+ metal ions from the motherboard leaching solution.}, issn = {2597-9914}, pages = {161--168} doi = {10.14710/jksa.25.4.161-168}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/44314} }
