摘要：

The aggregation of a monoazo acid dye was studied with osmometry. The osmotic coefficients of the dye were measured in aqueous solution and in 0.01 M potassium chloride. The mean aggregation numbers were calculated on the basis of the spherical cell model of dye in the solution. The results showed that the aggregation process is more distinctive in the presence of a simple electrolyte, probably because of the screening effect of the salt ions. (C) 1997 Elsevier Science Ltd.
