A new technique, dual-system and double-wavelength spectrophotometry has been developed. The method is based on the selection of the wavelength pair in 2 independent colored complex systems. By suitable choosing of R and L systems both the anti-interference ability and the sensitivity could be effectively increased, and its adaptability is better than that in the conventional double-wavelength spectrophotometric method. This new method has been theor. deduced and experimental proved in the simultaneous determination of Cu(II), Ni(II) and Cd(II), Mn(II) pairs.
