Separation of SO42- from simulated aqueous solution with the technology of foam fractionation was studied by using (1-hexadecyl)trimethyl ammonium hydroxide as the surfactant.

In order to develop the new desalination method which has the virtues of simple equipments and technology, non-pollution and low cost, a foam fractionation technology of removing CuSO4 from the simulated aqueous solution was studied by using dodecylbenzenesulphonic acid and (1-hexadecyl)trimethyl ammonium hydroxide as surfactant .

Study of dynamic interfacial tension of 3-dodecyloxy-2-hydroxypropyltrimethylammonium chloride and alkanes;

The ternary phase diagram of 3-dodecyloxy-2-hydroxypropyl trimethyl ammonium bromide(R_(12)TAB)/benzyl alcohol/water system was drawn based on experimental data.

The phase diagram of a ternary system composed of 3-dodecyloxy-2-hydroxypropyl trimethyl ammonium bromide(R12TAB),n-butanol and water was mapped out with the scope of various regions identified.

Both critical micelle concentration(CMC) and the counter ion association degree (K) of aqueous dodecyltrimethylammonium bromide (DTAB) solution systems have been simultaneously determined by bromide ISE.
