Determination of metal-bioligand complexes stability constants using analysis of buffer capacity spectra

摘要

BUFFER CAPACITY (b) is a quantitative characteristic of the buffer substances properties whose acid-base titration curves can be described by the dependence of the current value of the titrant concentration (acid or alkali) in the solution (C_(#gamma#)) from the the pH. The main peculiarity of burrfer capacity is the property of additivity, according to which the buffer capacity of a system over the whole pH range (#beta#_(sum)(pH)) is equal to the sum of the partial buffer capacities of all N components of the system (#beta#_j(pH)).
