The use of sodium diethyldithiocarbamate and ammonium iodide as complexing agents for the extraction of tellurium from botanical materials is investigated. Flameless atomic absorption spectrophotometry is used as the method of analysis. The acids used to wet ash the samples are examined for their contribution to interferences in the extraction and analysis processes. The extract ion parameters needed for complete extraction of the tellurium are described. The instrument parameters required for the most precise and accurate analysis of tellurium are described. The two extract ion processes are compared to determine which method is more suitable for the extract ion of tellurium from botanical materials.
