Abstract

Synthesis of organo-clay from natural bentonite with several surfactants using sol-gel methods has been conducted. The objective of this work is to modify the surface properties of the natural bentonite using several surfactants molecule. The modified materials can be further applied as composite materials, adsorbent and catalyst. The kind of surfactants which used on this work is HDTMA-Br (Hexadecyl Trimethyl Ammonium Bromide), TMA-Cl (Tetra methyl Ammonium Chloride) and PVA (Poly Vinyl Alcohol). The temperature for material synthesis was 80oC and it was agitated with hotplate magnetic stirrer for 5 hours. In order to characterize the structure of organoclay that has been synthesized, X-ray diffraction and nitrogen adsorption with BET methods were performed. The XRD data showed that surfactant cause increasing of inter layer d-spacing of bentonite. The organo-clay that synthesized by intercalation bentonite using HDTMA-Br 0.75% showed the highest inter layer d-spacing, while intercalated bentonite uisng PVA and TMA-Cl described similar inter layer d-spacing. The pore size distribution of organo-clay was at micropore range, which was widest surface area and biggest pore volume showed by intercalated bentonite using TMA-Cl 0.75 %.
