New liquid membrane technology for simultaneous extraction and stripping of copper(II) from wastewater

Stripping dispersion hollow fiber liquid membrane containing PC-88A as carrier and HCl for transport behavior of trivalent dysprosium

“…In homeostatic reaction system under ideal condition, all of these above individual transport fluxes can be taken for equality [12,[15][16][17][18][19].…”

“…If the diffusion process is described by the Fick's law, the transport flux of each step is given as follows [15][16][17][18][19]:…”

Uptake of Palladium Using Liquid Emulsion Membrane Technique

“…However LM techniques have not been adopted to large scale industrial processes yet (Zhang et al, 2000;Danesi et al, 1987;Gu et al, 2003;Lin et al, 2004;Neplenbroek et al, 1992;Bechiri et al, 2008;Zha et al, 1995) primarily due to lack of emulsification and deemulsification steps in ELM and SELM processes and membrane resistance in BLM and HFCLM processes etc. (Ren et al, 2007).…”

Transport of Tb3+ in Dispersion Supported Liquid Membrane System with Carrier P507

“…However, LM techniques have not been adopted for large-scale industrial processes, 9,11,12,[21][22][23][24][25][26][27] primarily due to the lack of longtime stability, hard to operating of the emulsification and de-emulsification steps in ELM and SELM processes, and larger membrane resistance in BLM and HFCLM processes, etc. 28 For the purpose of resolving these above difficulties in the conventional LM systems, a new liquid membrane technique, named dispersion supported liquid membrane (DSLM), 29 was proposed. The effect of various experimental parameters on the transport of rare earth Tb 3＋ ions was investigated.…”
