Abstract
The direct thermo-AAS method using a graphite or quartz-lined graphite sample cup and a hydrogen-argon or acetylene-air flame was used in th e evaluation of the volatility of metals from complex matrices in the temperature range 50-2000 degrees C. The thermo-AAS principle was empl oyed to solve problems related to toxic metal emission from high-tempe rature technologies. The volatility of tin in PVC matrix, cadmium in s ewage sludge, thallium in cement technology, and lead in pigment is di scussed in parallel with reference measurements. (C) 1995 Academic Pre ss, Inc.
