Recent Achievements in Polymer Bio-Based Flocculants for Water

The next type of modified chitosan flocculant was synthesized by reaction of carboxymethyl chitosan (Chito-CTA) with quaternary ammonium reagent. The amphoteric chitosan-based polymer was prepared by adding 3-chloro-2-hydroxypropyl trimethyl ammonium chloride to the Chito-CTA solution, which improves polymer solubility and increases its applicability as flocculant in water treatment [ 92 ].

A series of novel chitosan-based magnetic flocculants FS@CTS-P(AM-DMC) was prepared by molecular structure control. The characterization results showed that FS@CTS-P(AM-DMC) had a uniform size of about 21.46 nm, featuring a typical core-shell structure, and the average coating layer thickness of CTS-P(AM-DMC) was about 5.03 nm.

To solve the shortcomings of poor solubility, low cationic strength, and small molecular weight of chitosan (CTS), acryloyloxyethyl trimethyl ammonium chloride (DAC) and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) were introduced into the amino group of chitosan by graft copolymerization, and the modified chitosan flocculant CTS-DAC-AMPS was successfully prepared.
