- Can polymer inclusion membranes be used to remove metal ion from wastewater?
- Separation based on the use of polymer inclusion membranes (PIMs) with the advantage of simultaneous extraction and stripping has emerged as a promising approach for efficient and selective metal ion removal and/or recovery from wastewaters or electronic waste.
- Are polymer inclusion membranes suitable for metal ion separation and recovery?
- On the contrary, polymer inclusion membranes (PIMs), another type of liquid membranes, often have relatively higher long-term stability while retaining the advantages of SLMs. Therefore, PIMs have attracted growing interest for metal ion separation and recovery.
- Are liquid membranes a promising technology for metal removal?
- To address the issues of conventional membrane filtration, liquid membranes have emerged as a promising technology for metal removal. The commonly used liquid membranes at present are supported liquid membranes (SLMs) due to their high selectivity, operational simplicity, low solvent inventory, and low energy consumption .
- Is liquid membrane filtration a good option for metal removal?
- However, conventional membrane filtration has the issues of membrane fouling, unsatisfactory selectivity for small ions and short lifetime of the membrane , , , . To address the issues of conventional membrane filtration, liquid membranes have emerged as a promising technology for metal removal.
- Which plasticizer is favourable for high mass transfer through PIMS?
- According to the Stokes-Einstein equation, plasticizers with low viscosity are favourable for high mass transfer through PIMs. Plasticizers of higher dielectric constants facilitate dissociation of ion-pairs, thereby facilitating the transport properties of the membranes .
- What is membrane filtration?
- Membrane filtration is an emerging technology for separation of ions or molecules due to its high efficiency and relatively low costs , , . However, conventional membrane filtration has the issues of membrane fouling, unsatisfactory selectivity for small ions and short lifetime of the membrane , , , .
