Using Light Scattering to Screen Polyelectrolytes (PEL) Performance in Floccula...
Rasteiro, Maria G.; Pinheiro, Ineide; Garcia, Fernando A. P.; Ferreira, Paulo; Hunkeler, DavidFlocculation of precipitated calcium carbonate (PCC) was monitored using light diffraction spectroscopy (LDS). Four cationic polyacrylamides of high molar mass and with different degrees of branching, all copolymers of acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride (Q9), were tested. LDS supplied information about the kinetic curves for flocs growth and also for the flocs structure evolution. F...
