摘要

A method was developed for online analysis of vaporized cadmium in any exhaust gas by coupling an inductively coupled plasma spectrometer to the gas outlet of a laboratory fluidized bed reactor. A calibration device was set up and implemented, and a standard gas synthesis protocol was developed to obtain quantitative data. The calibration method was validated by heating Cd-spiked porous alumina particles in the fluid bed. Mass losses in the solid phase were measured and compared to the amount of cadmium detected by the online gas monitoring system. The mass balance was satisfying, thus validating the method, which was finally applied satisfactorily in the case of combustion of Cd-spiked realistic artificial waste.
