Sintesis Dan Karakterisasi Silika Gel Dari Limbah Kaca Serta Aplikasinya Pada Kromatografi Kolom

Abstract

Silica gel synthesis from glass waste have been carried out with activation and purification method by using hydrochloride acid. Hydrochloride acid were varied 8 N, 10 N, and 12 N to observe optimum concentration in purification of silica gel and component separation in chromatography column. Gravimetric analysis result showed 12 N hydrochloride acid produce ~100 % silica. XRD and FTIR analysis revealed that synthetic gel silica was amorphous where its IR absorption bands were at 3426 cm-1, 1620 cm-1, 1080 cm-1, 772 cm-1 and 478 cm-1. The absorption bands agreed to standard gel silica and spectrum. The most effective HCl in gel silica synthesis was 12 N, caused by its ability to separate color component in a column. The synthetic silica that can be applied as stationary phase in column chromatography.

Sintesis Dan Karakterisasi Xerogel Hasil Kopresipitasi Dari Pasir Pantai Panjang Bengkulu

“…Silikon Dioksida (SiO2) merupakan salah satu mineral jenis oksida yang telah banyak dimanfaatkan potensinya untuk berbagai kebutuhan komersial sehari-hari [1], antara lain sebagai bahan utama industri gelas dan kaca [2]. Silika Gel merupakan salah satu bentuk kimia dari SiO2 [3], yang memiliki keistimewaan yaitu mampu berperan sebagai adsorben [4], yang dapat disintesis dari berbagai sumber bahan baku untuk di antaranya dari limbah gelas kaca [5], abu sekam padi [6], abu ampas tebu [7], abu terbang [8], kaolin [9], dan lain-lain. Adsorben Silika Gel di dalam keadaan kering dikenal juga dengan nama Xerogel [10].…”

Preparation of C4-silica Gels from Waste Glass and Tributylamine

“…Silica gels could be modified to be a non-polar stationary phase by impregnating some non-polar organic compounds on the surface of silica gels [4,5]. Khosravan and Saljooghi had altered the surface of silica gels by applying 2-aminothiophenol to isolate an Mn 2+ ion for column chromatography [6].…”
