Separation and preconcentration of trace amounts of gold from water samples prior to determination by flame atomic absorption spectrometry
A preconcentration/separation procedure is presented for the solid phase extraction of trace gold(III) as its rubeanic acid (dithiooxamide) chelate on silica gel, prior to determination by flame atomic absorption spectrometry. The influences of analytical parameters including pH of the aqueous solut...
