Notes:
Abstract The effect of citric acid on the stability of a hematite sol consisting of uniform spherical particles has been studied as a function of pH and of the acid and sol concentrations. The critical coagulation concentration decreases significantly with increasing pH and so does the critical stabilization concentration due to charge reversal. The phenomena observed are directly related to chemisorption of the citrate ion on metal oxide particles.
