Abstract: In this work, a novel solidified floating organic drop microextraction (SFODME) technique was developed and coupled with electrothermal atomic absorption spectrometry (ETAAS) for the determination of trace silver in water samples. Diethyldithiocarbamate (DDTC) was used as a chelating agent and 1-undecanol as the extraction solvent. The optimum experimental parameters for preconcentration of Ag(I), such as pH, chelating agent concentration, extraction solvent volume, extraction time and interfering ions, were i…
