Synthesis of Amorphous Aluminosilicates from Bintan’s Red Mud as Alumina Source

Nanostructured Gamma Alumina from Amorphous Precursors

Introduction Nanocrystalline gamma-phase (γ) alumina is among many polytypes of alumina that find extensive applications as a catalyst and catalytic supports. The most useful properties these aluminas provide as catalyst supports are high surface area and welldefined porosity. These properties result primarily from the nano-scale crystalline character of the alumina. The problem is that both th...

Adsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud

Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive r...
