In this paper a special effect of aluminium and nickel on the spectral lines of alkaline-earth metals being present in low concentration was studied. During the study a sharp difference could be obtained in the behaviour of atomic and ionic lines, therefore among the lines investigated both atomic and ionic ones were included. The effect of Ni and Al was investigated in a wide concentration range in case of Be, Mg, Ca and Sr. In case of each of the four alkaline-earth element a significant difference in the depression of the signal could be observed with increasing Al or Ni concentration among atomic and ion lines.

A thermodynamic method of the global Gibbs energy variation calculation for describing heterogeneous equilibria of transformations of calcium, strontium, and barium polyvanadates, that occur in systems MeO-V2O5-H2O, where Me is the alkaline earth element, has been developed and used. Its quintessence consists in the thermodynamic analysis of the real conditions of various processes on the basis of their total thermodynamic characteristics. On the basis of the selected thermodynamic data for involved species, the thermodynamic stability areas of solid polyvanadates towards the solution pH and vanadium and alkaline earth metal ion concentrations in heterogeneous mixtures have been established, taking into account the complex formation reactions in multicomponent heterogeneous systems. The existing experimental data confirm the results on the thermodynamic stability of polyvanadates obtained in this paper.
