Ekstraksi Silika Dari Palm Oil Fly Ash (Pofa) Sebagai Adsorben Untuk Pengolahan Air Gambut

---

Palm Oil Fly Ash (POFA) is one of the solid wastes from the combustion
of shells and palm fiber in the boiler. It is potential as an adsorbent because of its
high silica content. The purpose of this research is to study the effect of the ratio
raw materials to solvents and processing time to the production of silica extracted
from POFA and to determine the efficiency removal of organic matter, color, and
Fe in peat water. POFA was extracted with NaOH 3 M at a temperature of 85 oC,
stirring speed of 150 rpm, and silica settling using HCl 1 M. The conditions of the
extraction process varied were the ratio of raw materials to solvents 1:8, 1:10,
1:12 and processing time 2; 2,5; 3; 3,5 hours. The extracted silica product was
then tested using XRF and XRD analysis. XRF analysis results showed 49.84%
SiO2 and silica peak was in the range of 2θ= 20,78o (d= 4,27Å). The POFA
surface area is 3.85 m2/g and has increased after extraction to 6.26 m2/g. The
silica product is then applied as an adsorbent for removal of organic matter,
color, and Fe in peat water. The results showed the highest removal for organic
matter, color, and Fe in peat water were 46.15%, 69.33% and 39.30% in the ratio
of raw materials to solvent of 1:12 and processing time of 3,5 hours. The results
of peat water treatment in this study still haven’t reached the quality standards, so
it needs further processing so that it can be used as clean water.
