| Abstract | : | A simple, cheap and environmentally friendly analytical method of Cd(II) analysis in the aqueous system has been developed by immobilization of 1-(2-pyridilazo)-2-naphtol (PAN) in polyvinyl chloride (PVC) matrix and nitrophenyl octyl ether (NPOE) as a plasticizer. Upon contact with Cd(II) in the solution, the color of sensor membrane changes from dark yellow to dark red, which is due to the formation of Cd(II)–PAN complex. The best sensing results were obtained at pH 8.0 and ?max 558 nm. The dimension of the proposed sensor membrane was 0.8 cm x 2 cm with a thickness of 0.05 mm, the volume of sample was 2 mL with the Cd(II) concentration range of 0– 1.2 ppm. The detection limit of the method was found to be 0.048 ppm and molar absorptivity of 4.42 x 105 L mol-1 cm-1 . The proposed methods have been applied in the determination of Cd(II) in water samples after addition of internal standard with recovery 98.88-100.75%. |
