Abstract

For utility of unburned carbon particles from Coal combustion by-products (CCPs), this study aims at making unburned carbon particles as adsorbent in wastewater effluent control. An activation treatment with temperature of 850°C and under steam atmosphere had proceeded on unburned carbon particulars, and the effects on adsorptive capability were appeared with results from tests of iodine number and methylene blue adsorptive capacity. The result shows that unburned carbon products demonstrated larger adsorptive capability after activation treatment. While the product with specific surface area up to 500m2/g, its iodine number becomes more than 1000mg/g from the initial ∼100mg/g, its methylene blue adsorptive capacity becomes 90ml/g from ∼10ml/g in methylene blue solution of a concentration of l200ppm. Conclusively, unburned carbon particles from CCPs are supposed to make market adsorbents by appropriate activation.
