内容記述 | A spectrophotometric method for the determination of μg amounts of copper in sample solution is presented. Copper reacts with oxine, 2-methyl-oxine, 5,7- dichloro-oxineand 5,7-dibromo-oxine to form water-insoluble colored complexes. These complexes are directly extracted into mo1ten naphthalene. The extracted mixture of copper complex and naphthalene is separated from aqueous solution by decantation, dried on a fi1ter paper and dissolved in dimethylformamide. The absorbance of the solution is measured at a given wavelength of 420 nm against the reagent blank and μg amounts of copper is determined spectrophotometrically. The other factors such as pH, amounts of reagent,naphthalene and diverse salts are studied. The molar absorptivity, sensitivity and relative standard deviation are evaluated. | |||||
