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 rest of the cadmium is released through human activities, such as manufacturing processes, etc. Human intake of cadmium takes place mainly through diet like liver, mushrooms, shellfish, mussels, cocoa powder and dried seaweed [4]. One of the main resources for cadmium accumulating in the human body is the extensive use of tobacco.…”

Diacetylmonoxime-3-amino-4-hydroxy benzoyl hydrazone (DMAHBH) is used as a novel chromogenic organic reagent for the determination of Cadmium (II) with spectrophotometer. The novel chromogenic organic reagent − diacetylmonoxime-3-amino-4-hydroxy benzoyl hydrazone (DMAHBH) gave yellow colored water soluble complex with Cd (II) in buffer (pH = 8.0−9.0) medium. The color complex shows maximum absorbance at λ = 378 nm. The system obeyed Beer's law in the concentration range of 0.5035−5.0535 µg/ml. The optimum Cadmium (II) concentration range for accurate determination as evaluated from Ringbom plot was 0.5035−5.0535 µg/ml. The molar absorptivity and Sandell's sensitivity were 2.94 . 10 4 l . mol -1. cm -1 and 0.0036 µg/cm 2 respectively. Cadmium (II) forms M:L (I:I) color complex with DMAHBH and stability constant of the complex was found to be 8.58 . 10 7 . Soil samples were analyzed for the determination of Cadmium (II) present, using the proposed method. This developed method was applied for the determination of Cadmium (II) in soil and cigarette samples and good analytical results.
