Abstract:
This work intends to recover ions of heavy metal from wastewater using reactive extraction by nanofibers-supported liquid membrane in a microchannel. The use of supported liquid membrane enables simultaneous extraction and stripping processes. In this study, the NSLM was applied in a microchannel to minimize mass transfer resistance, hence improving overall performance of the extraction. Copper (II) was used as a model ion, while di-2-ethylhexyl phosphoric acid dissolved in kerosene was used as the extractant. The extractant was supported by a thin layer of polyvinylidene fluoride nanofibers to form a thin immiscible layer, i.e., liquid membrane, within the microchannel. The feed solution was supplied on one side of the liquid membrane for copper extraction, while hydrochloric acid was supplied on the other side for stripping of copper ions from the liquid membrane. Effects of applied voltage in electrospinning for nanofibers fabrication, thickness of microchannel in the microreactor, and initial metal concentration in the feed stream on the extraction efficient were investigated and reported
