| description | Isolation of peat soil humic acid and its application for adsorption-reduction of
Au(III) have been conducted. Humic acid was isolated from peat soil that was collected
from Rawa Pening, Central Java. Isolation of humic acid from peat soil was based on
conventional alkaline extraction. Humic acid was extracted from peat soil with NaOH
0.1 M, then precipitated with 0.1 M HCl, and purified with 0.1 M HCl/0.3 M HF 1/1.
The isolated humic acid was characterized by FTIR spectroscopy, then applied for
adsorption reduction of Au(III). Isothermic adsorption capacity on adsorption
reduction process of Au (III) also were studied. The gold metal formed was confirmed
by XRD diffractogram, and photo optical microscope. The adsorption capacity with
Langmuir isothermic model for humic acid was 192 mg/g. Peaks of gold particles in the
difractogram are 2 = 38, 44, and 64. |
