Abstract
The possibility to use sodium diethyldithiocarbamate (Na-DDTC) for bismuth (III) concentrating by the micellar extraction at cloud point (CP) temperature and subsequent atomic absorption spectrometry (AAS) determination was investigated. Under the optimum conditions, preconcentration of 10 ml of water sample in the presence of 0.05% non-ionic surfactant (NS) Triton X-114, 5ˣ10-5 M sodium diethyldithiocarbamate at pH 6 permitted the detection 8 µg1-1 bismuth in water samples after cloud point extraction.
