TL;DR: The adsorption isotherms and kinetics indicate that adsorptions of Cr(VI) and MO by CS-CTA-MCM both follow a homogeneous monolayer chemisorption process, and chromium could be efficient removal together with MO at suitable pH conditions.

TL;DR: Different flocculation mechanisms play key roles at various pH levels, resulting in substantially varied flocculations kinetic processes under three pH conditions, systematically evaluated by light scattering in combination with fractal theory, as well as by traditional turbidity and zeta potential measurements.

TL;DR: In this paper, strong cationic chitosan-based graft copolymer flocculants (3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CTA) modified CHITOSAN-graft-polyacrylamide, denoted as chitosa-CTA-g-PAM) were studied systematically, both at the laboratory scale and at the pilot scale.

TL;DR: A dual-function starch-based flocculant, carboxymethyl-starch-graft-aminomethylated-polyacrylamide (CMS-g-APAM), was designed and prepared by a simple method and interpretation of the zeta potential and floc properties showed that simple charge neutralization was the dominant mechanism of flocculation in acidic medium.

TL;DR: In this article, the effects of different chemical additives including dispersant and stabilizer on the solid loading, viscosity, rheological behavior and static stability of coal water mixtures have been investigated.
