Study on removal of cadmium from wastewater by emulsion liquid membrane

Study on the Expression of Organic Anion Transporting Polypeptide (oatp2a1) in Rat with Spleen Deficiency Syndrome and the Exploration of Clinical Significance

“…Water as solute liquid carrier, its contents includes essence of water and grain, water, dampness (food metabolites, drug metabolites, endogenous and exogenous toxins, etc.) [4][5][6].The generation, distribution and excretion of water is a complicated physiological process involving functions of various viscera, especially the lung, spleen, and kidneys, and spleen's function is the most important.…”

Emulsion liquid membrane for heavy metal removal: An overview on emulsion stabilization and destabilization

“…3. While, other study showed that the best stirring speed to ensure a good stability of the W/O emulsion and to enhance the interfacial area available for mass transfer on the copper removal was 200 rpm [30] and for cadmium extraction was 280 rpm [75]. Based on these studies, it can be said that the optimum stirring speed which gave better emulsion stability and rate of metal extraction is very closely depend to the conditions of parameters used, such as the emulsion compositions and the equipment, and types of metal to be extracted.…”

“…Conversely, lower V int /V m leads to a thicker and more stable membrane phase, which impedes the diffusing process and increases the consumption of membrane phase [74]. Mortaheb et al [75] also revealed that the strength of emulsion wall and its resistance against breakage increase with decreasing V int /V m . In the experiment of Wan and Zhang [40], V int /V m can affect the surfactant concentration at the interface of membrane/aqueous phases and in the bulk membrane phase, thus affecting emulsion swelling.…”

Enhancing performance of hybrid liquid membrane process supported by porous anionic exchange membranes for removal of cadmium from wastewater

“…Among the conventional methods [3,4], liquid membrane processes (LMs) are powerful techniques for removal and recovery of cadmium in low contents [5][6][7]. The advantages of these techniques are their low cost and energy consumption, simple operation, high efficiency, and capability of continuous operation [8][9][10].…”
