Co-Adsorption of Mixed Cationic/Non-Ionic Surfactants on a Quartz Surface
Autor: Mohsen Nikoorazm, Jayashree Nagarkar, Sharad Dixit
Publikováno v: Adsorption Science & Technology, Vol 17 (1999)
The co-adsorption of binary mixtures of tetradecyltrimethylammonium bromide (TTAB) and nonyl phenyl ethoxylates (NP-n series) from their aqueous solutions on to quartz has been studied. None of the ethoxylates adsorbed on to the quartz when alone, bu
