摘要：
It is shown that carboniferous samples can be analyzed by injecting them directly into an electrothermal atomizer of an atomic absorption spectrometer as an aqueous suspension stabilized by a surface-active substance. The main factors affecting the stability of the suspension and the metrological characteristics of the procedure are considered; methods for their estimation and approaches to the optimization of the analysis conditions are proposed. A rapid procedure for the determination of silver in carboniferous samples is developed that reduces the time of analysis by several times.
