| description | Adsorption of Pb
2+
and SO4
2-
ions by N-cetyl-N,N,N-trimethylammonium
(CTA
+
) cationic surfactant modified bentonite has been studied. The research was
started by washing bentonite of Thailand using 1.5 M sulfuric acid followed by
modification using CTA
+
surfactant with concentration as much as twice of cation
exchange capacity (CEC). The CTA
+
modified bentonite was then used for
adsorption of Pb
2+
and SO4
2-
ions. The bentonite samples were characterized by
FTIR spectrometry and X-ray diffraction methods, whereas the analysis of Pb
2+
cation was measured by AAS and the analysis of SO4
2-
anion was measured by
UV-Vis spectrophotometer. Results showed that major mineral component of
bentonite was montmorillonite and acid activation process caused dealumination.
The adsorption process of Pb
2+
and SO4
2-
on CTA-bentonite followed the
Langmuir adsorption isotherm. The value of adsorption capacity was
7.42 x 10
-5
mol/g for SO4
2-
and 1.38 x 10
-5
mol/g for Pb
2+
. Meanwhile, the
adsorption energy was 23.90 kJ/mol for SO
4
2-
and 33.28 kJ/mol for Pb
2+
. The
adsorption capability of Pb
2+
on natural bentonite > activated bentonite > CTA
bentonite and the adsorption capability of SO4
2-
on CTA-bentonite > activated
bentonite > natural bentonite. |
