Spectrophotometric Determination of Copper (II) with 4-Methyl-Tetrahydrobenzofurano-(6, 7-b)-Coumarin I.

使用4-甲基-四氫苯並呋喃-(6.7-b)-香豆素作銅(II)之光譜測定

並列摘要


Synthesis of 4-methyl tetrahydrobenzofurano-(6, 7-b)coumarin (I) and spectrophotometric determination of copper (II) with I has been described. The system obeys Beer's law in the concentration range of 1.6~6 ppm of copper (II) and molar absorptivity is 12,700 at 370 nm. Sensitivity was found to be 0.0036 μg cm^(-1) for 0.001 absorbance. The effect of various parameters have also been reported.
