Talmi, Y; Feldman, C

This review was organized in terms of the main steps and topics characterizing all trace analysis: sample pretreatment and dissolution, solution stability, preconcentration, isolation and determination. Pretreatment methods included wet ashing, dry ashing, oxygen combustion, and fusion. Methods used for preconcentration included: coprecipitation and adsorption, liquid-liquid extraction, and volatilization. The methods used for determination were: (1) molecular absorption-spectrophotometry; (2) radiochemical techniques; (3) electrochemical techniques such as amperometric titrations, polarography, and coulometry; (4) x-ray fluorescence spectroscopy; and (5) atomic spectroscopy including atomic emission spectroscopy, atomic absorption spectrometry, and chromatographic methods. 161 references, 5 figures.
