Chemex (stream sediments) MIBK solvent extraction atomic absorption spectroscopy (Sb)

Chemex, stream sediments; MIBK solvent extraction atomic absorption spectroscopy (antimony)

General Methodology:

For the determination of antimony, a 2 gram sample was digested with concentrated HCl in a hot water bath.  The iron was reduced to Fe(II) and the Sb extracted with trioctyl phosphine oxide MIBK and measured with atomic absorption spectroscopy with background correction.
