Sintesis Silika Gel Menggunakan Limbah Kaca Laboratorium Sebagai Sumber Silika

ABSTRACT
Silica gel is a material widely used in the industrial sector as an adsorbent, filler, and catalyst support. It can be synthesized from various natural sources containing silica (SiO₂), one of which is laboratory glass waste. In this study, silica gel was synthesized from laboratory glass waste through the production of sodium silicate, followed by precipitation using HCl solution. The aim of this research was to investigate the effect of varying HCl concentrations (1N, 3N, and 5N) on the yield and characteristics of the resulting silica gel. Crushed glass waste was reacted with 3N NaOH solution to produce sodium silicate solution. This solution was then reacted with HCl solution at various concentrations to form a hydrogel. The hydrogel was dried in an oven at 105°C to produce dry silica gel. The results showed that HCl concentration affected the amount of silica gel obtained, with the highest yield of 4.48 grams at 5N HCl concentration. Characterization using Fourier Transform Infrared (FTIR) spectroscopy indicated the presence of characteristic functional groups of silica such as silanol (≡Si–OH) and siloxane (≡Si–O–Si≡), and analysis using X-Ray Diffraction (XRD) revealed that the resulting silica gel was in an amorphous phase.
Keywords: amorphous, glass waste, sodium silicate, silica gel.
