โœฆ Synopsis

Adsolubilization behavior of 2-naphthol on alumina with adsorption of sodium dodecyl sulfate (SDS) at pH 3.5 in the presence of 10 mmol dm -3 NaCl was reexamined. The adsolubilized amount of 2-naphthol increased sharply and reached a maximum, then decreased with SDS concentration. The decrement of the adsolubilized amount began below the critical micelle concentration of SDS. From the dispersion state of the alumina suspension and the SDS adsorption isotherm, it is demonstrated that the decrement of adsolubilization of 2-naphthol is not due to the partition of 2-naphthol between the SDS adsorbed layer and SDS micelles, but is due to the difference of SDS adsorption states such as monolayers and admicelles.

The adsorption kinetics of poly(vinylpyrrolidone) (PVP) and sodium dodecyl sulfate (SDS) on alumina particles at pH 3.5 has been studied by measuring the amount of PVP and SDS adsorbed and the dispersion stability of solid suspensions with time. Although PVP alone hardly adsorbs on alumina particles
