New Stoichiographic Methods for Separation and Determination of Components in Catalytic Processes

Malakhov VV and Dovlitova LS

In this paper, the fundamental concepts of stoichiography is presented which open up a new area to determine chemical composition, phase, molecular and ionic, of complicated mixtures of polyelement and polyphase inorganic substances. Doing it, there is no need to use standards of individual compounds and to get selective separation. At the same time, a high possibility occurs to determine quantitatively chemical composition of the mixture occurs. The general principles of two stoichiographic methods are set out: differential dissolution dedicated to analyze mixtures of solid inorganic compounds; ionic chromato-stoichiography to analyze composition of water solutions. Some examples are given concerning applications of the methods to analysis of heterogeneous and homogeneous catalysts.
