 Title    Ein neues Verfahren zur spektrometrischen Analyse von Metallkomplex-Lösungen A New Method for Spectrometric Analysis of Complex Metal Solutions  
 Abstract    A new simple method is given to analyse potentiometrically titrated and spectrophoto-metrically measured complex-solutions of the system AH ^ A -j-H3Ü+ and n • A + M^MA n . The absorbance coefficients of the metal complex MA n and the stability constants can be determined for each titration step by construction of the "extinction triangle" in the (two-dimensional) absorbance (E) diagram. It is not necessary to know the absolute pH value of the solution. The titration of 2-nitroso-l-naphthol-4-sulfonic acid/zinc sulfate in water is shown as an example.
