Background. Currently huge amount of work has been carried out to obtain interpolyelectrolyte complexes (IPEC) of chitosan with natural and synthetic polyanions. Presence of charge in the macromolecule on surface of IPEC particles could effectively immobilize oppositely charged of particles. In this regard, polyelectrolyte complexes are used for wastewater purification, targeted drug delivery, for the construction of different biomaterials, as well as biologically active and biodegradabled of agricultural preparations. At the present, time study of fundamental principles of obtaining IPEC of natural polyelectrolytes and creation of preparations based on nosshown scientific and applied interest. Purpose. The aimof study is obtaining thermodynamically stable interpolyelectrolyte complexes based on Bombyx mori chitosan and study their ability to bind with soil minerals. Methodology. At this work are used turbidimetric, potentiometric and conductometric titration, laser microelectrophoresis, elemental analysis, etc. Originality. For the first time, stoichiometric and non-stoichiometric Bombyx mori chitosan complexes were obtained and hoyghown the possibility of their applicotions as a structurant for soil erosion. Findings. Obtained IPEC chitosan Bombyx mori with macromolecules of Na-CMC. The composition and hydrodynamic dimensions of the complexes are revealed. It was established that at pH = 6.3 of, chitosan and Na-CMC interacted at 1: 0.34 molar ratio. The particle size of IPEC in solution ranges from 80 to 1000 nm and has ability to bind with soil minerals, forming strong crusts. It hos shown that polyelectrolyte crusts are durable to washing and mechanical stress, which in will be applied in soil erosion. Highlights: * biodegradable and environmentally products are included; * chitosan is non-toxic polymer and extracted from renewable natural sources; * interpolyelectrolyte complexes could be used in agriculture.
