Summary

The interaction between sodium carboxymethyl cellulose and acridine orange was studied by spectral method. The effect of the degree of polymerization and etherification on the binding of the dye was discussed. The binding value increases with an increase in the degree of the polymerization. The number of binding sites per unit glucose was larger than the degree of etherification. Therefore, the electrostatic interaction was probably not the predominant factor.

Zusammenfassung

Die Wechselwirkung zwischen Natriumcarboxymethylcellulose und Acridinorange wurde mit den spektroskopischen Methoden untersucht. Der Effekt des Polymerisationsgrades und des Verätherungsgrades bei der Verbindung mit Acridinorange wurde diskutiert. Die Bindungszahl nimmt mit dem Polymerisationsgrad zu. Die Zahl von den Adsorptionsstellen der Glukoseeinheit wird größer mit der Verätherung. Deshalb ist offensichtlich die elektrostatische Wechselwirkung kein vorherrschender Faktor.
