摘      要：An inductively coupled plasma atomic emission spectrometer （ICP-AES） was developed to continuously measure the heavy metals concentrations in flue gas in order to track the metal release *** system is devoted to the thermal treatment of metal-spiked mineral matrix, coal and municipal solid wastes in fluidized bed （850℃）.This method was used to study the kinetics of heavy metals *** optimum values of the gas flows from the 1200 W power generator were 0.1 L·min -1 for the sample gas and 0.2 L·min -1 for *** the thermal treatment of coal and municipal solid waste,Cd and Pb were released readily,while Zn was released at a lower level than Cd and *** formation of stable compounds such as ZnO·Al2O3 and CdO·Al2O3 from the reaction of heavy metals with fly ash particles could decrease heavy metals *** all cases, the experimental setup was successfully used to monitor the heavy metal release process during coal and solid waste thermal treatment.
