| description | The study of the ability of dithizone-immobilized natural zeolite for adsorption of
Ag+ and Zn2+ions has been done and the resultswere comparedwith those adsorbedby
unmodified active natural zeolite.
The research consisted of the study of the adsorption of Ag+ and Zn2+ions.
Adsorbent characterization was performed using Infrared Spectrophotometer, X-Ray
Diffiaction analysis. The study of the adsorption included pH optimization, adsorption
kinetic,isothermadsorptionand interactionspecies.The amount of Ag+ and Zn2+ions
adsorbed by two kinds of the adsorbent was determined by Atomic Adsorption
Spectrophotometer.
The result of adsorbent characterization showed that dithizone was successfully
loaded on the surface of active natural zeolite and the immobilization did not
significantly damage the cristallinity of zeolite. Adsorption study suggested that the
optimum condition of the adsorption of Ag+ and Zn2+ ions was at pH 6. Adsorption
kinetics parameter evaluated by Langmuir-Hinshelwood equation for Ag+ ion showed
that the adsorption rate constant of natural zeolite active was 1.0 x 10-3minute-I and that
of dithizone-immobilized natural zeolite was 3.0 x 10-3 minute-I. In addition, the
equilibrium constant of active natural zeolite was 8104 mor1L and that of dithizoneimmobilized
natural zeolite was 9630 morIL. Adsorption kinetics parameter evaluated
by Langmuir-Hinshelwood equation for Zn2+ ion showed that the adsorption rate
constant of natural zeolite active was 3.43 x 10-4 minute-I and that of dithizoneimmobilized
natural zeolite was 3.87 x 10-4 minute-I. In addition, the equilibrium
constant of active natural zeolite was 4118 morIL and that of dithizone-immobilized
natural zeolite was 4338 morIL. Isotherm adsorption parameter determined using
Langmuir-Hinshelwood equation for Ag+ ion showed that adsorption capacity of
dithizone-immobilized natural zeolite (1.264xlO-4mol/g) was higher then that of active
natural zeolite (1.029 x 10-4 mol/g). Adsorption equilibrium constant of dithizoneimmobilized
natural zeolite (8770.510 morIL) was higher than that of active natural
zeolite (6417.437 morIL). In addition, the activation energy of dithizone-immobilized
natural zeolite (22.494 kJ/mol) was found to be higher then that of active natural zeolite
(21.720 kJ/mol). Isotherm adsorption parameter determined using Langmuir-
Hinshelwood equation for Zn2+ ion showed that adsorption capacity of dithizoneimmobilized
natural zeolite (6.108 x 10-5mol/g) was higher then that of active natural
zeolite (5.189 x 10-5mol/g). Adsorption equilibrium constant of dithizone-immobilized
natural zeolite (18230.512 morlL) was higher than that of active natural zeolite
(9813.137 morI~). II! addition, the activation energy of dithizone-immobilized natural
zeolite (24.307 kJ/mol) was found to be higher then that of active natural zeolite (22.773
kJ/mol). Types of interactions that contribute to the adsorption of Ag+ and Zn2+
sequentially from the largest amount of complex formation, hydrogen ion exchange, ion
exchange, and entrapment. |
