Using the Chem3D Pro program, some empirical and semi-empirical orbital properties of urea, formaldehyde, urea-formaldehyde and 1,1’,1”-((2,4,6-trioxo-1,3,5-triazinan-1,3,5-tri)-tris(methylene))triurea The length and angular relationships of the bonds, optimization and calculation of the energy of the molecule, quantum chemical calculations of the studied compounds using the MM2 method are shown. The resulting samples were examined using IR spectroscopy and X-ray phase analysis. Also, in this article, the dependence of the sorption of some d-metals on the sorbent based on cyanuric acid on the pH environment was studied and the results were presented. In sorption, the optimal pH size corresponds to the pH size of the formation of the acidocomplexes of the respective metals. Accordingly, the level of sorbation of the ions of the metals studied (SA+MFO (III)) in the sorbent increases in the following series: Mn (II) < Fe (II) < Co (II) < Ni (II) < Zn (II) < Pb (II) < Hg (II) < Cd (II) < Cu (II) < Ag (I).
