Abstract

The objectives of this research were to prepare montmorillonite and of chromium oxide-montmorillonitecomposite by intercalation of oxide of chrom into the silicates interlayer of montmorillonite, and to characterizesome of their physical and chemical properties. The characterization indicated that the basal spacing d001 wasincreased from 14,11 in montmorillonit to 15,55 in chromium oxide-montmorillonite; specific surface area wasincreased from 69,71 m2/g to 240,40 m2/g; total pore volume was also increased from 0,05 mL/g to 0,128 mL/g; andchrom content also increased from 0,007% (w/w) to 17,16 % (w/w).
