Exploration of heavy metal ions transmembrane flux enhancement across a supported liquid membrane by appropriate carrier selection

Reply to comment on “Exploration of heavy metal ions transmembrane flux enhancement across a supported liquid membrane by appropriate carrier selection” [Chemical Science Engineering 62 (2007) 6032–6039]

“…A recent computational study also gave very large formation energies for the complexation of metal ions with different binding sites of poly(amidoamine) dendrimers (Tarazona-Vasquez and Balbuena, 2004). Nevertheless, the calculated formation energies for metal-carrier complexes provide us a first-principles guideline for selecting a favorable carrier for the supported liquid system, which we verified as workable not only in a Cd(II) system (Lv et al, 2007) but also in a Cu(II) system (Yang et al, 2006).…”

His comments are interesting and could be helpful in our further studies.…”

Supported Liquid Membrane Using Hybrid Polyethersulfone/Graphene Flat Sheet Membrane for Acetic Acid Removal

“…A symmetric membrane is suitable for the SLM process due to the amount of forces exerted on both sides of the membranes are identical, thus the membrane stability improved during the SLM process. 5,6 It can be seen on Figure 2(a) that pristine PES membrane showed a symmetric structure with cylindrical microvoids uniformly distributed throughout the cross section of membrane. Addition of graphene induced the dense sublayer on the bottom of the membrane and the distance between two cylindrical microvoids was increased.…”

Effect of VIPS fabrication parameters on the removal of acetic acid by supported liquid membrane using a PES–graphene membrane support

“…The force that exerted on both sides of the symmetric membranes is likely to be almost the same, thus, there is the possibility of improving the overall SLM process. 35 Further increase of CBT to 60 C had resulted in decreasing of the AA removal to 78%.…”
