Organic Solvent Effect for Atomic Absorption Sensitivity

Abstract

The organic solvent give greatest sensitivity enhancement were used in solvent
extraction studies. When extracting (100ml) of aqueous solution with (50ml) of organic
solvent. It is possible to detect silver at 5x 10-3 ppm, Galium at 4x10-3 ppm, Germanium
at 8x10-3 ppm and copper at 2x10-3 ppm based up on the original aqueous phase
concentration by using flame atomic absorption technique. Silver, galium, germanium
and Copper standard curves were prepared by extraction (100ml) of aqueous solution
with (20ml) of organic solvent. Enhancement of atomic absorption sensitivity have been
observed in most cases.
