Determination and Use of Stability Constants

This book describes potentiometric methods for determining stability constants and explains how these constants can be used to describe metal ion speciation in complex environmental and biological systems. It also provides three original computer programs on a disk for calculating stability constants and for using stability constants to calculate concentrations of molecular species in solution.
The author gives examples of calculations for simple metal chelates, for metal complexes of large organic molecules, and for mixtures containing several metal ions and complexing agents in aqueous solution. They also describe common errors in calculating stability constants and how to avoid them.
This carefully revised second edition is now even more useful to the reader, and, in particular, to those who make use of the program disk. Each program has been revised to improve speed, control, and error trapping.Neue Entwicklungen wie die graphische Uberprufung der Gute von Rechenergebnissen werden beschrieben und mit Illustrationen veranschaulicht. Ebenso beschrieben werden Entwicklung und Einsatz einer umfassenden Datenbank, die zur Bestimmung einzelner molekularer Spezies in Multikomponentensystemen (wie z.B. den komplexen flussigen Systemen der belebten und unbelebten Natur) geeignet ist.

Das Buch eignet sich nicht nur als praktisches Handbuch fur Einsteiger in das Gebiet der Untersuchung von Metallkomplexen in Losung, sondern enthalt auch einheitliche Richtlinien fur all jene, die sich bereits mit der Messung von Stabilitats- konstanten von Metallkomplexen beschaftigen oder solche Stabilitatskonstanten fur eigene Arbeiten nutzen.
