【 摘 要 】

The study is focused on the development of new spectrophotometric reagent for metal ion determination. The synthesis was through the condensation reaction between amino compounds and carbonyl compound. The spectrophotometric activities of the new reagent was studied using chromium (VI), cobalt (II), Hg (II), Cu(II) and Pb (II) respectively. The use of Jenway UV/VIS spectrophotometer (double beam) model 6505 was used to elicit the wavelength of maximum absorbance of the five metal complexes. Another Jenway UV/VIS spectrophotometer (single beam) model 6305 was employed for the determination of variation in absorbance at various concentrations of the metal ion at constant reagent’s concentration to draw the calibration curve. The curve finally showed the efficiency of the reagent up to 5 x 10-4mole dm-3of the metal ion concentration.
