Simultaneous determination of Au(III) and Cu(II) with 1-phenyl-1,2-propanedione-2-oximethiosemicarbazone (PPDOT) on solid phase

Multi-element coprecipitation for separation and enrichment of heavy metal ions for their flame atomic absorption spectrometric determinations

“…The interferic effects of matrix components of real samples especially highly saline samples including seawater, urine are important problem in the determination of heavy metals [36][37][38][39][40][41][42]. The effect of some foreign ions ( Table 2) which interfere with the determination of metal ions by the proposed method or/and often accompany heavy metal ions in various real samples was examined.…”

Development of an Analytical Method for Trace Gold in Aqueous Solution Using Polyurethane Foam Sorbents: Kinetic and Thermodynamic Characteristic of Gold(III) Sorption

“…7 A simple and accurate method based on the adsorption of the gold(III)-diethyldithiocarbamate complex on Amberlite XAD-2000 resin prior to its determination of gold in environmental samples has been developed by flame atomic absorption spectrometry after elution with 1 mol L -1 HNO3 in acetone. 8 Gold was also determined by electrothermal atomic absorption spectrometry after electrochemical preconcentration on a graphite ridge probe used as a working electrode and sample support.…”
