Abstract
In the system of ammonium thiocyanate—hydrochloric,the Co(Ⅱ) ions were separated by extraction of its thiocyanate anionic complexes with methyl isobutyl ketone (MIBK) from abundance of manganese. Cobalt in organic phase was determined by flame atomic absorption spectrometry. The method had good selectivity and high sensitivity. The range of determination of the method was 0.2~20?μg/g.
