  • Adsorption of polyacrylamide on oxide minerals

    2003-2-21 · Experimental Procedure. The depletion method is used todetermine the amount of polymer adsorbed. The mineral isprewetted with the solvent before the addition of polymer. Thepreconditioning (wetting) time is determined by introducing themineral into the solvent and measuring the pH change of thesuspension with time. A constant bulk pH is taken to be anindication that equilibrium is attained. The polymer solutionis then added and the suspensionconditioned further at a rmalsolid/liquid = 0.03. The polymer adsorption time is determinedfrom kinetic studies,and adsorption is consideredto be completewhen the adsorption density remains constant with time. Bothprewetting and polymer conditioning of the suspensionare ac-complished by a wrist-action shaker. For all the studies, thepreconditioning and polymer conditioning times are determined,and the appropriate times chosen are 3 and 4 h, respectively.Longer polymer conditioning times are not used, so that anyPO88ibledegradationof polymer …
