An efficient, rapid, simple, and highly selective dispersive liquid–liquid microextraction based on solidification of floating organic drop (DLLME-SFOD), combined with flame atomic absorption spectrometry was developed for preconcentration and determination of trace amounts of cobalt in water samples. In this method, an appropriate mixture of acetone and 1-undecanol was injected rapidly into th...
