Abstract

Fly ashes from a lignite fired power plant and a municipal incinerator were leached for 3 hours using 0.1N HC1. Leachate was analyzed for Cd and Mn and plots of concentration versus time for these elements show Cd, a surface adsorbed element in the combustion process, to be rapidly removed from the ash particles in the initial four or five minutes of leaching. Manganese, a fly ash matrix element, is leached at a more constant rate as the ash praticles are dissolved. Total Cd and Mn concentrations in the incinerator fly ash are greater than total concentrations of these elements in the lignite fly ash.
