Abstract

The adsorption of caustized cassava starch on goethite, Kaolinite and quartz has been investigated using model 5500 Atomic Absorption / inductively coupled plasma spectrometer to determine the residual concentrations in the solution .The effect of such variables as pH and starch concentration on adsorption has been studied. Also the effect of reagentization time on the flocculation pH of pulp and starch concentration on the flocculation behaviour was studied. Both polymer adsorption and the flocculation of goethite, kaolinite and quartz are enhanced as the pH decreases .The amount of polymer adsorbed rises at first and then approaches a saturation value.

KeyWords: Adsorption, Flocculation, reagentization.
