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
