Ultrafiltration of Micellar Solutions in the Presence of Electrolytes

Ultrafiltration of Surfactant Solutions

“…• C) using a procedure similar to that described by Tondre et al (19)(20)(21)(22). The cells were stirred AMICON 8010 and AMICON 8050 with a 10-and 50-ml volume, respectively.…”

“…However, industrial streams to be treated usually contain various quantities of salt, which may affect the properties of the micellar solutions, possibly involving changes in the micelle structure and changes in viscosity. The micellar solution is then affected and the flux of the permeate decreases (22). The effect depends both on the electrolyte and on the surfactant.…”

On the Behavior of Micellar Solutions in Tangential Ultrafiltration Using Mineral Membranes

“…changed, in the case of tangential ultrafiltration not only the operating pressure is important, but also the retentate flow In a previous paper (1) we have recalled the growing rate. This work was aimed at investigating the effect of interest for separation processes based on the use of orgapressure, flow rate, salt, and pH on the flux of permeate and nized molecular systems (2) and especially micellar syson the amount of surfactant passing through the membrane.…”

Removal of Radioactive Cations and Anions from Polluted Water Using Ligand-Modified Colloid-Enhanced Ultrafiltration

“…These new separation techniques allow selective removal of target ions in a single-phase continuous process and have the potential to remove pollutant cations and anions simultaneously. Recently other groups have reported applications of LM-CEUF for removal of radionuclides and toxic metal ions using surfactant micelles as the coloidal phase [10][11][12][13][14][15][16]. This research project was done in collaboration with workers at the Lawrence Livermore National Laboratory Laboratory where studies involving enriched radionuclides were carried out.…”
