RelevanceCalcium phosphates are part of biogenic and pathogenic mineral
formations. Interaction of organic and mineral components is
important in such processes of biogenic crystallization, as the
formation of bone matrix mammals, as well as the emergence and
growth of pathogenic entities. There are some assumptions,
according to which the basis of the processes of mineralization
lies in the adsorption interaction of free amino acids and
associated protein molecules with inorganic components of
biological liquids. In particular, such processes include
adsorption-desorption interaction. The mechanism of their
interaction is not fully understood.
In this regard, relevant studies aimed at studying the regularities
of adsorption and desorption of amino acids on calcium
phosphates.

The purpose of this paper is to study the specific features ofthe adsorption-desorption interaction of amino acids with
calcium phosphates while varying the pH of the solution.
Tasks:
The synthesis of hydroxylapatite;
Setting up an adsorption and a desorption experiments;
The study of adsorption and desorption of amino acids with
varying parameters of the initial solution.
