TL;DR: The influence of structural elements of the chitosan-based flocculants on their flocculation properties are emphasized in this review by examining different flocculations mechanisms and their applications in the treatment of various wastewaters containing different pollutants.

TL;DR: Improvement is attributed to the formation of stronger interactions between Hg and the amide groups of PAM branches for chelating effects in CS-PAM-MCM, and the removal of the three aforementioned metal ions may follow a similar adsorption manner through a homogeneous monolayer chemisorption process.

TL;DR: In this article, a series of amphoteric starch-based grafting flocculants (3-chloro-2-hydroxypropyl trimethyl ammonium chloride modified starch-graft poly(acrylamide-co-acrylic acid)) denoted as SCPAMPAA were successfully synthesized with different grafting ratios and used for the removal of different charged contaminants from water.

TL;DR: Three-dimensional excitation-emission matrix spectra and direct cell morphological observation under scanning electron microscopy reveal that the starch-based flocculants exhibit better antibacterial effects on the Gram-negative bacterium E. coli than on the gram-positive bacterium S. aureus.

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.
