Abstract
The objective of this study is to measure the purification
and characterization of the quality of quartz sand from Pasir Putih village,
South Pamona district. The purification was done to increase the pureness of
the silica by soaking the sample with HCl 2M then was titrated using aqueous to
reach the pH of 7 (neutral). The sample was characterized using the XRF and
XRD. Moreover, the element content of SiO2 (Silica) after the purification based
on the results of the analysis was 99,88%. Therefore, the element can be used
as the raw material for solar cell. Matching the result of the XRD analysis
with the software Search Match shows that the purification of the sample SiO2
contains the crystal trigonal system (Hexagonal axes) with the orientation
field.
