Abstract

This research study aims to study the potassium acetate concentrations on the increase of kaolin interlayers through intercalation and heat treatment processes. The effect of six different concentrations of potassium acetate : KAC (3, 4, 5, 6, 7, and 8 M) were used. The soaking process was applied on clay to form clay-acetate complex. X-ray diffraction (XRD) results indicated that the higher Kac concentration caused the higher intercalation ratio. However, a concentration of 5 M KAC was chosen to gain an optimum intercalation ratio if green chemistry was taken into account. The clay-intercalating complex was carried out completely at room temperature for 3 days. The complex was heat treated to delaminate the expanded layer. SEM and XRD confirmed that Kac especially influence on kaolin structure by expanding the kaolin layer.
