Abstract

The adsorption of neutral macromolecules and ionic surfactants on various sols, as well as the effect of these substances on the stability of the sols were investigated. Sols having high recrystallization rate do adsorb both macromolecules and ionic surfactants; the adsorption isotherms are of the high affinity type. However, neutral macromolecules are not adsorbed at all by sols having low recrystallization rates. With these the adsorption isotherms of the ionic surfactants are of the Langmuir type. The stability of the arsenic trisulphide sol is affected by macromolecules and surfactants in a way differing from that of other sols examined. The As2S3-sol, too, has the highest recrystallization rate. In all cases the interfacial energy is supposed to be the determining factor.
