| description | It was conducted study on synthesis of zeolite A from coal bottom ash in
PLTU Paiton East Java and its application to the cobalt(II) adsorption. Synthesis
of zeolite A was conducted by the combination of melting method of NaOH and
its hydrothermal treatment using microwave. Hydrothermal treatment was
conducted at the temperature of 100 degree C for 3 hours. The coal bottom ash and the synthetic zeolite A was characterized by FTIR, XRD, SEM and GSA using the
method of BET. The adsorping study involved the influenced parameter of pH,
kinetic adsorption and its isothermal adsorption of Co(II). The number of
adsorpted Co(II) was analyzed using AAS.
The analytical result using AAS showed that the coal bottom ash of PLTU
Paiton contained silica and alumina that were the raw products synthesis of zeolite
A. The characterization using FTIR and XRD showed that the melting process of
coal bottom ash of NaOH produced the silicate and alumina amorf. The optimal
condition of adsorption 10 mL Co(II) by 40 mg coal bottom ash and 40 mg zeolite
A were reached at pH 7. The adsorption 10 mL Co(II) time for coal bottom ash
of zeolite A was started to be stable at the 30 minute. The kinetical adsorption
10 mL Co(II) by 40 mg coal bottom ash and 40 mg zeolite A tended to follow the
kinetical order of one model of Santoso et al, compared by the kinetical order of
one model of Langmuir-Heinshelwood. The adsorption of 10 mL Co(II)
increased to 150 ppm for the 40 mg zeolite A and 60 ppm for the 40 mg coal
bottom ash. The adsorption of 10 mL Co(II) by 40 mg zeolite A was processed
chemically and followed the isothermal adsorption model of Langmuir with the
adsorption capacity, the equilibrium constant (K) and the adsorption energy were
5.19 x 10-4mol/g, 1.85 x 104mol-1L and 24.59 kJ/mol, respectively. The
adsorption of 10 mL Co(II) by 40 mg coal bottom ash was processed physically
and followed the isothermal adsorption model of Freundlich with the adsorption
capacity and the equilibrium constant (K) were 0.04 mol/g and 1.24 mol-1L,
respectively . The study results showed that the zeolite A could be synthesized
from the coal bottom ash and the adsorption of 10 mL Co(II) by 40 mg zeolite A
was higher than that was reached by the 40 mg coal bottom ash. |
