Yield and Pore-size Distribution of Pyrolysis Products of Organic Compounds as Chemical Modifiers in Electrothermal Graphite Furnace Atomic Absorption Spectrometry†

Abstract

Yields of pyrolysis products and pore-size distribution of amorphous carbon produced from organic chemical modifiers, such as ascorbic acid, glucose and sucrose, for electrothermal atomization atomic absorption spectrometry were examined: the pyrolysis yield (for which ascorbic acid>glucose>sucrose) and the pore-size distribution are independent of the modifier used.
