Surface| Zusammenfassung: | State and structural characteristics of water bound to starch and an influence of nanosilica, quercitin immobilized on nanosilica’s surface and organic solvents (chloroform and dimethylsulfoxide) were studied using low-temperature lH NMR spectroscopy, NMR-cryoporomelry and quantum chemisty methods. It was established that interfacial water was in a cluster state. Additionaly, solid phase stabilized clusterization of weakly associated water (3 — 4 % of total water concentration) in the presence of weakly polar chloroform medium. All interfacial water appeared to be strongly bound without addition of dimethylsulfoxide and a portion of this water tranforms into weakly bound in a mixture of solvents that testify significant re-organization of bound water structure in the presence of dimethylsulfoxide. |
