Abstract: [cze] [eng]
Pred samotnou charakterizáciou interakcií dextranu s tenzidom SDS boli skúmané vlastnosti roztoku dextranu vo vode a v chloride sodnom. Najprv boli merané denzitometricky, pričom bola skúmaná ich hustota a ultrazvuková rýchlosť v závislosti na koncentrácii a teplote. Ultrazvuková rýchlosť bola ďalej meraná pomocou ultrazvukovej spektroskopie s vysokým rozlíšením. Následne boli skúmané interakcie dextranu s povrchovo aktívnou látkou SDS, kde cieľom bolo zistiť kritickú agregačnú a micelárnu koncentráciu. Before the itself of characterization interactions of dextran with surfactant SDS, there were investigated properties of dextran solution in water and in sodium chloride. At first it was measured by densitometer, where their density and ultrasonic velocity was investigated, depending on concentration and temperature. The ultrasonic velocity was further measured by high resolution ultrasonic spectroscopy. Subsequently the interactions of dextran with surfactant SDS was examined to determine the critical aggregation and critical micelle concentration.
