title: [The mistakes of E. Dinc's double divisor-ratio spectra derivative method].
abstract: Double divisor-ratio spectra derivative method has been developed and applied to determining two ternary mixtures simultaneously by E. Dinc. In fact, E. Dinc's double divisor-ratio spectra derivative method is completely wrong. It can not be applied to determining ternary mixtures simultaneously. This paper proves the Mistake of E. Dinc's method in both theory and practice.
