ADSORPTION OF INDIGO CARMINE DYE USING CETYLTRIMETHYLAMMONIUM BROMIDE (CTAB) SURFACTANT MODIFIED ZEOLITE
ABSTRACT: Research of indigo
carmine dye adsorption using natural zeolite modified by cetyltrimethylammonium
bromide (CTAB) surfactant has been done. The purpose of this study was to
modify the natural zeolite using CTAB surfactant and to determine its ability
on the adsorption of indigo carmine dye. The stages of the study included the
activation of zeolites, modifying zeolites using CTAB surfactant and adsorption
test of indigo carmine dye. The results showed that the zeolites could be
modified by CTAB. They were then characterized by the existence of FTIR
absorption band at wavelengths of 1404.18 cm-1 and 2800-3000 cm-1. The various
concentration of indigo carmine (5, 10, 15, 20 ppm); contact time (15, 30, 45
minutes) and pH (3, 4, 5, 6, 7, 8, 9) were studied and the highest condition
was reached at the 45 minutes, pH= 3 and indigo carmine concentration of 20 ppm
for 0.5 and 1 mM CTAB (15.35% and 23%) and indigo carmine concentration of 5
ppm for 10 mM CTAB (96.18%). The adsorption of indigo carmine tended to
increase with increasing the concentration and contact time and decreased with
increasing the pH.
