Abstract

In this work phillipsite-rich tuff (P) was modified by using amounts of cetylpyridinium chloride (C) equivalent to 70% and 140% of the zeolite external cation exchange capacity (ECEC). Accordingly, composites were denoted as PC-70 and PC-140. Prepared composites were characterized by ATR-FTIR spectroscopy. Additionally, to test the stability of surfactant molecules attached to the tuff surface, composites were extensively washed with distilled water, and zeta potential of unwashed and washed samples was measured. FTIR spectra confirmed presence of C in both composites. Zeta potential measurements showed that composite containing surfactant in the amount below the ECEC value (PC-70) has much higher stability and thus is a more appropriate adsorbent for potential practical application for removal of different pollutants.
