Physical and chemicalmethods of research kompleksonov and their complexes

For composition and structure definition kompleksonov, and in this case, optical isomerides kompleksonov, derivatives of succinic and glutaric acids, we used such methods as the element analysis, poljarimetrija and Ik-spectroscopy.

The majority of applied methods of studying of processes kompleksoobrazovanija with classical kompleksonami, as a rule, considers only mono biligandnye complexes, at the same time protonirovannym and gidroksokompleksam the insufficient attention though under certain conditions they include a significant part of the general concentration of diffident metal is paid, and in some cases can be and in general prevailing. Thus, it is necessary to consider their formation in a solution.

Definition of constants of stability of complexes formed in a solution by potentiometric methods yields the direct information on hardness of complexes and the indirect information on composition of the found out complexes.

To add and specify the information on a structure kompleksonatov the metals, received by other methods studying of these complexes by methods of atomic absorption spectrometry, thermogravimetry and Ik-spectroscopy allows.

V.I.Spitsina, L.I.Martynenko, N.A.Kostrominoj's [33-35] devoted to studying of processes kompleksoobrazovanija by methods the works rn - potentiometries, high-res spectrographies, NMR, EPR allow to characterise to the full a pattern of formation of complexes in a solution. At use of these methods there is a possibility of research step kompleksoobrazovanija, direct definition of concentration of consistently formed and simultaneously existing complexes
In a solution. Some physical and chemical methods (potentiometry, a spectrophotometry) it is possible to define composition and constants of stability not only averages, but also protonirovannyh and gidroksokompleksov [36]. In work [37] function which describes behaviour of a number protonirovannyh and gidroksokompleksov has been entered.
