Effect of pH on anionic polyacrylamide adhesion: New insights
Abstract. pH can affect the physicochemical properties of the membrane and the anionic polyacrylamide (APAM), thus changing the degree and situation of membrane fouling. However, limited research has been conducted to determine its mechanism based on the extended Derjaguin–Landau–Verwey–Overbeek (XDLVO) theory.
