An Insight into Colloidal Gas Aphron Drainage Using Electrical Conductivity Measurement

Journal: Iranian Journal of Chemistry and Chemical Engineering 2008

Maryam Moshkelani, Mohammad Chalkesh Amiri

In the present paper Electrical Conductivity (EC) of Colloidal Gas Aphron (CGA) suspensions was measured for anionic and cationic surfactants (Sodium Dodecyl Sulfate (SDS) and Tetradecyl Trimethyl Ammonium Bromide (TTAB)). Experiments were made for different concentrations of SDS (6, 8.1, 10 mM) and TTAB (2, 3.51, 5 mM). CGA drainage behavior was observed and measured using 1 liter measuri...
