Preparation and Properties of Interpolymer Complexes Capable of Soil Structuring

Resumo

Complexation between biopolymers, chitosan cationic polyelectrolyte and sodium carboxymethyl cellulose anionic polyelectrolyte, was studied. The composition of the interpolymer complex formed was determined by conductometry and Fourier IR spectroscopy. The interpolymer complex and the initial complex-forming polymers were used for the first time as soil-structuring agents in urban soils. Treatment of urban soil with the interpolymer complex led to aggregation of soil particles and improved the water permeability of the soil.
