Abstract:Using the 4-CH3O-salphen, the spectrophoto-metric quantitative analysis of Cu(II) ion in aqueous solution was performed. The optimum condition for the quantitative analysis of Cu(II) ion was determined as the following; the concentration of 4-CH3O-salphen is 2.0×10 -4 mol/L, ratio between solvent DMSO and water is 50/50(v/v), pH is 5.5. After 1 hr water incubation at 55 o C and then the absorbance measurements at 388 nm, a calibration curve (ε=3.6×10 4 mol -1 cm -1 ) with a correlation coefficient (R 2 =0.9963… Show more
