Summary

While studying the adsorption of sodium poly(acrylic acid) (Na-PAA) on the surface of commercial ball clays, it was noticed that higher additions of PAA resulted in a dark supernatant in systems prepared at pH 6. These previously adsorbed species interfered with the technique chosen to determine the amount of PAA adsorbed on the clay surface. Samples of clay were washed at pH 9.5 to remove these species for identification and characterization, and the adsorption of PAA on the refined clay was determined. The adsorption levels compared to the untreated clay approach the predicted levels from a model based upon the mineralogy of kaolinite.
