The Cost

Coal fly ash was used to synthesize X-type zeolite by alkali fusion followed by hydrothermal treatment. Characteristics of the various Fly ash samples were carried out. Coal proximate analysis was done. Batch experiment was carried out for the adsorption of some heavy metal ions on to synthesized Zeolite. The cost of synthesized zeolite was estimated to be almost one-fifth of that of commercial 13X zeolite available in the market.

Waste Coal

The waste coal fly ash was utilized to synthesize zeolite by alkaline fusion method through orthogonal test. The copper oxide was loaded on the zeolite by dipping method. The optimal ratio of coal fly ash to sodium hydroxide, ratio of liquid to solid, calcining temperature and crystallization time were determined to be 1.2, 9, 700°C and 10 h, respectively. The CuO dipped zeolite was applied to treat the acid red GR wastewater and the obtained color and COD removal rates were 83.80% and 99.88%, respectively. The XRD pattern showed that the NaA type zeolite phase was formed in the experiment.

Waste Coal

This paper reviews the pathways that large volume utility wastes can take which can cause environmental effects. Potential interactions of the environment with land-disposed utility wastes include: (1) effects on local air quality, (2) efforts on soils and vegetation, (3) phytotoxicity, (4) groundwater effeccts, (5) effects on surface waters, and (6) disposal site washout. Both natural and engineered mitigating mechanisms are reviewed.
