Abstract: Kaolin-ZVI (Zero Valent Iron) composite has been synthesized through reduction method. This study aims to synthesize and investigate the characteristics of kaolin-ZVI composite using X-ray diffraction, infrared absorption and gas adsorption on the surface of these material; the adsorption performance of Kaolin-ZVI composite investigated on adsorbed of Cr (VI). In this study, the Kaolin used is using Indonesian Natural. Kaolin-ZVI Composite synthesized from Fe (III): BH4-ratio was 1: 9 and ZVI the synthesized from Fe (III): BH4-ratio was 1: 2. The results showed that the fraction of kaolin modified with ZVI suffered destruction. Based on the analysis using XRD known that Fe0 formed on kaolin-ZVI, and ZVI; iron compounds such as iron oxide and magnetite maghemit are dominating in the two samples. The results of the analysis using the GSA shows the specific surface area of kaolin, kaolinite-ZVI, and ZVI respectively for 13.29; 58.37; and 40.99 m2/g. The adsorption of Cr (VI) indicate that the kaolin, kaolinite-Zvi, and Zvi can adsorb Cr (VI), respectively 39.87; 70.65; and 132.90 mg/L.DOI: http://dx.doi.org/10.15408/jkv.v0i0.4650
