Boccio, A. Asuero, A. Sayago] A bilogarithmic hyperbolic cosine method for the spectrophotometric evaluation of stability constants of 1 : 1 weak complexes is developed and applied to data found in the literature. The method devised does not require any approximations and the variables of the final equation proposed are well separated, being, in addition, the abscissa free from error, which facilitates the application of least squares analysis. The proposed method also provides a closed-scale representation of variables, unlike other plots, and agrees well with the nonlinear regression method. Pleiades Publishing, Ltd., 2007 Boccio M.
