Arsenic content in fly ashes and its leaching characteristics were investigated for two different coals to control arsenic concentration in waste water from a land reclamation site. The fly ash samples were corrected from an ESP in a large scale pulverized coal combustion process. To know the effect of size distribution on the leaching rate, fly ashes were sieved in six classifications, and their arsenic content and leaching were measured by a direct determination using GF-AAS. The leaching rate of arsenic was not influenced by the particle size distribution, however, pH of a leaching test strongly affected the leaching rate of arsenic.
