Sintesis Natrium Silikat (Na2sio3) Dari Silika (Sio2) Pasir Pantai Bengkalis

ABSTRACT
Sodium Silicate is a raw material that is widely used as a filler in the detergent, soap
and toothpaste industries. Sodium silicate can be synthesized from silica (SiO2),
which can be obtained through the extraction process from silica-containing materials
such as sand, clear glass waste or straw. In the synthesis of sodium silicate, silica is
reacted with NaOH solution at a relatively low temperature of 95-105 ° C. This study
aims to determine the effect of the molar ratio of NaOH and SiO2 reactants obtained
from Bengkalis beach sand, namely at the ratio = 2: 1, 3: 1 and 4: 1 on the resulting
conversion of sodium silicate. The synthesis process of sodium silkate begins with
reacting 4M NaOH solution with 10 grams of silica from Bengkalis sand,
accompanied by heating at 100 + 3oC for 1 hour and stirring constantly at 600 rpm.
The resulting sodium silicate mixture is separated by filtrate and precipitate by
filtering. The sediment is then burned using a furnace at 400oC for 4 hours. From the
analysis using Fourier Transform Infrared Spectroscopy (FTIR), the spectral pattern
of the synthesized sodium silkate compound with typical silica absorption is the
absorption of silanol (≡Si-OH) and siloxane (anSi-O-Si≡).
Keywords: filler, extraction, sodium silicate, silanol, silica
