| Abstract | : | An optical chemical sensor for determination of Cd(II) in aqueous solution has been developed by immobilizing 1-(2- pyridylazo)-2-naphtol (PAN) in poly(methyl methacrylate) (PMMA) as a matrix and 2-nitrophenyl octyl ether (NPOE) as a plasticizer. The adsorption of Cd(II) causes the color of the membrane to change from yellow to red-orange with the maximum absorbance (?max) at 556 nm. The sensor membrane gives the best response towards Cd(II) ion at pH 8.5, after 120 minutes of contact time, at 2 ppm Cd(II), and 2 mL solution. A linear Cd(II) calibration curve can be developed in the concentration range of 0.8 - 1.8 ppm with R2 = 0.960. The limit of the detection and limit of quantification are 0.041 ppm and 0.126 ppm, respectively. The molar absorptivity is found to be 2.3 x 105 L mol-1 cm-1 . The proposed sensor membrane has been applied to the determination of Cd(II) in the river water with internal standard addition method. The observed percent recovery is in the range of 100.24 – 107.52% |
