“…It is based on chemical sorption of cadmium ions onto a minicolumn packed with Amberlite XAD-2 resin loaded with TAM reagent [54]. After being preconcentrated, cadmium was eluted by 0.50 mol L −1 hydrochloric acid of cadmium was 4 and 9%, regarding repeatability and reproducibility respectively.…”

A procedure for the determination of trace amount of cadmium after adsorption of its 1-nitroso-2-naphthol-3,6-disulfonic acid chelate on Ambersorb 572 has been proposed. This chelate is adsorbed on the adsorbent in the pH range 3-8 from large volumes of aqueous solution of water samples with a preconcentration factor of 200. After being sorbed, cadmium was eluted by 5 mL of 2.0 mol L(-1) nitric acid solution and determined directly by flame atomic absorption spectrophotometery (FAAS). The detection limit (3sigma) of cadmium was 0.32 microg L(-1). The precision of the proposed procedure, calculated as the relative standard deviation of recovery in sample solution (100 mL) containing 5 microg of cadmium was satisfactory (1.9%). The adsorption of cadmium onto adsorbent can formally be described by a Langmuir equation with a maximum adsorption capacity of 19.6 mg g(-1) and a binding constant of 6.5 x 10(-3) L mg(-1). Various parameters, such as the effect of pH and the interference of a number of metal ions on the determination of cadmium, have been studied in detail to optimize the conditions for the preconcentration and determination of cadmium in water samples. This procedure was applied to the determination of cadmium in tap and river water samples.

“…The content of cadmium at low concentrations has been determined by several techniques, including flame atomic absorption spectrometry (FAAS) [4,5], electrothermal atomic absorption spectrometry (ETAAS) [6], inductively coupled plasma-mass spectrometry (ICP-MS) [7], inductively coupled plasma optical emission spectrometry (ICP-OES) [8,9], and instrumental neutron activation analysis (INAA) [10].…”
