Relevance
Calcium phosphates are part of bioorganic 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 of amino acids on calcium phosphates.

The purpose of this paper is to study the specific features of
the adsorption-desorption interaction of amino acids with
calcium phosphates while varying the pH of the solution.
Tasks:
The synthesis of hydroxylapatite, the study of its properties
when the pH of the solution is varied;
Setting up an adsorption experiment;
The study of adsorption of amino acids on hydroxylapatite
with varying parameters of the initial solution;
The study of desorption of amino acids.
