Title : Enhancing the Performance of Kaolin for Organic Dye Removal via Compositing with Goethite
Della Kharisma, , Zaenal Abidin, , Cecep Kusmana, , Herry Suhardiyanto, , Masayuki Sakakibara,
Abstract : Kaolin is an aluminosilicate mineral with low adsorption and degradation ability for organic dye molecules. Herein, to improve its adsorption properties, kaolin was composited with goethite, which is known to absorb and degrade dye molecules. The kaolin/goethite composites were synthesized via a simple low-temperature method. Specifically, a ferric ion solution and sodium hydroxide were consecutively added to commercial kaolin, and the mixture was aged at 40 °C for seven days. The synthesized co
