In this study, the widely applied modified Smoluchowski model of flocculation kinetics based on the existence of two simultaneous processes, namely aggregation and breakup, is further developed by combining it with the fractal theory. The floc properties including the floc size and fractal dimension are extracted using online data acquisition through light scattering technique and combined into the...
In the present work, a novel amphoteric chemically bonded composite flocculant (carboxymethyl chitosan-graft-polyacrylamide, denoted as CMC-g-PAM) was successfully prepared and used to flocculate the kaolin suspension. The flocculation performance of CMC-g-PAM in acidic, neutral, and alkaline conditions was systematically evaluated by light scattering in combination with fractal theory, as well as...
Base on the principle of absolute quantification of size exclusion chromatography (SEC), a light scattering (LS) detector coupled with a concentration detector (refractive index detector) is utilized to determine the compositions of complicated binary mixtures. A theoretical analysis predicts that the response factors for both LS and RI detectors are linear functions with the composition of any specified...
