Utilization of fly ash and red mud for thermal storage ceramics

Investigation of arsenic removal parameters by a new nano-hybrid adsorbent produced from red mud and fly ash

Two common waste materials, red mud and fly ash, were used to produce a new nano-hybrid adsorbent by heat treatment with alkali addition. The new zeolitic structure formation of the hybrid adsorbent was revealed using the BET surface area, XRD, and SEM analyses. This hybrid adsorbent was utilized to remove arsenic from synthetic and real waste waters by batch and column adsorption experiments. ...

Multi-Technique Application for Waste Material Detection and Soil Remediation Strategies: The Red Mud Dust and Fly Ash Case Studies

Utilization of Biomineralization Processes with Fly Ash for Carbon Sequestration

Introduction The Department of Energy (DOE) Energy Information Administration estimates atmospheric greenhouse gas releases may exceed 8 billion metric tons by the year 2010 heightening its international environmental concern. Carbon dioxide will dominate the greenhouse gases (Kane and Klein, 1997) and the majority of these results from the use of fossil fuels. With viable replacement of fossil...

Utilization of nSiO2, fly ash, and nSiO 2/fly ash composite for the remediation of triphenyltin (TPT) from contaminated seawater.

The removal of triphenyltin chloride from contaminated simulated seawater with adsorption method was discussed. The adsorbents used are fly ash, nSiO2, and nSiO2/fly ash composite. The results showed that the adsorption of the adsorbents increases with increase in the adsorbent dose, contact time, pH, stirring speed, initial TPT concentration, and decreased with increase in temperature. The ads...

Physical and Chemical Properties of Sintering Red Mud and Bayer Red Mud and the Implications for Beneficial Utilization

Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...
