Adsorption of dodecyl- and octadecyltrimethylammonium ions on a smectite and synthetic micas

摘要

Adsorption of n-alkyltrimethylammonium ions with alkyl chain lengths of C12 and C18 on the natural Kunipia F smectite (KN) as well as on synthetic fluorotetrasilicic mica (TSM) and fluorotaeniolite (TN) whose CECs are 119, 170 and 215 meq/100 g, respectively, was studied. The C and N contents were determined and thermosgravimetric and XRD analyses were carried out.
