Abstract
Tungstate sorption kinetics were determined in batch-wise experiments on a surfactant-modified
zeolite (SMZ), prepared by treatment of a clinoptilolite sample by HDTMA-Br (HDTMA being the
hexadecyltrimethylammonium cation). The influence of various parameters was studied, namely
pH, effect of temperature and initial Tungstate concentration with a maximal removal value at
equilibrium of about 80% .
Key words: Surfactant modified Clinoptilolite, Batch, Water, HDTMA.
