Objective: To determine copper by the double-wavelength spectrophotometric. Method: A new double-wavelength spectrophotometric method has been developed for the determination of copper. Result: The experimental results shown in the best condition the apparent molar absorptivity of copper was 0.005 0-0.160 mg·L-1. Conclusion: The method is applied to the direct determination of copper in Chinese traditional medicine of with satisfactory results.
