Recovery of these metals can help not only protecting environment but also balancing their supply and demand. Supported liquid membrane with strip dispersion (SLMSD) is among the promising methods to recover metals from waste sources. Theoretically, simultaneous extraction and stripping using hydrophobic membrane would allow zero-waste as well as high metal concentration in receive phase. This research investigated the ability of recovering different metals such as indium, europium, yttrium using SLMSD. The investigation proved that SLMSD was able to remove more than 99.5 % metal ions from wastewater or leaching solution. High metal concentration was obtained by adjusting feed to strip volume ratio. |
