Plant Growth on ‘Fly Ash’

Tribal dependence on fly ash in Korba

Introduction Fly ash, a by-product from power plants, is a powdery gray material that is stored in large ash dykes or ponds. This ash is used in making bricks and in cement factories. Fly ash is considered to be a major pollution problem as it is dispersed into the air and pollutes bodies of water. However, for the local tribal populations of Korba district, Chhattisgarh state, fly ash is becom...

Chemical Reaction of Fly Ash

In a previous paper, Brouwers and Van Eijk [1] presented a theoretical study on the dissolution (reaction) of pulverised powder coal fly ash. This fly ash was modelled as hollow spheres, and a shrinking core model was derived for these hollow spheres that contain two regions (an outer hull and an inner region). The obtained analytical equations were applied to the dissolution experiments by Pie...

Adsorption of tungsten onto zeolite fly ash produced by hydrothermally treating fly ash in alkaline solution.

Fly ash (FA) was hydrothermally treated in an alkaline solution to produce zeolite fly ash (Z-FA). The properties of the FA and Z-FA were investigated. The amounts of tungsten (W) adsorbed onto the FA and Z-FA surfaces were evaluated. Z-FA was produced by hydrothermally treating FA in an alkaline solution. The specific surface area and pore volume of the Z-FA were greater than those of the FA. ...
