Conclusions
-
1.
A new approach to the investigation of freshly precipitated Fe3+ hydrogels, based on the concepts of the polymer structure of the primary particles of the precipitate, was developed.
-
2.
A new methodology was proposed for the study of the processes of formation and properties of precipitates of Fe3+ hydrogels, constructed on the basis of a combination of the methods of chemical and complex thermal analysis.
-
3.
The composition of the primary particles is determined by the conditions of formation of the precipitates. At pH below 7.5, the primary particles contain anions of the salt as an element bearing a structural load, and not only playing the role of a counter ion.
-
4.
A mechanism was proposed for the formation of primary particles of precipitates of Fe3+ hydrogels from polymer subunits with the structure and composition characteristic of the given hydroxide.
