· UL has no effect on the stability of clay particles, because of its low charge density. Previously, anionic polyacrylamide (APAM), with a high charge density (-4.2 meq/g) stabilized kaolin particles better than APAM with a low charge density (-1.8 meq/g), which was attributed to the maximum adsorption of high charge APAM on the clay surface .
