METHOD FOR PREPARING A SAMPLE FOR THE ELECTROTHERMAL ATOMIC-ADSORPTION DETERMINATION OF CONTENT OF SILVER IN SOLID CARBON-CONTAINING MATERIAL

摘要

The proposed method for preparing a sample for the electrothermal atomic-adsorption determination of content of silver in solid carbon-containing material by using a spectrometer consists in inserting weighed quantity of carbon-containing material suspension stabilized with 0.1 % sodium lauroylsulfonate into the spectrometer atomizer.
