Adsorption and Aggregation of Surfactants in Solution
No adsorption of PAM onto silica was observed; however, PAM was found to adsorb onto hematite and alumina at pH 3.0. At pH 9.5, there was no adsorption of PAM onto alumina. Given the lack of adsorption of PAM onto silica, which has strong Bro¨nsted acid sites, it was concluded that PAM TABLE 2 Polymer
