Amphoteric synthetic organic polymer flocculant

Amphoteric synthetic organic polymer flocculant refers to a water-soluble polymer containing both positive and negative charge groups on the molecular chain.
It is one of the main research directions for the synthesis of organic polymer flocculants with special effects
.

Compared with water-soluble anionic or cationic polymers containing only one kind of charge, amphoteric synthetic organic polymer flocculants have unique properties

The polyampholyte refers to that the anionic group and the cationic group exist in the same macromolecular main chain
.

According to the nature of its monomer unit, it can be divided into strong acid and strong base type, strong acid and weak base type, weak acid and strong base type and weak acid and weak base type; according to the different sequence structure, it can be divided into random, alternating, grafted and embedded.

Polylactam is shown in that the cationic group and the anionic group exist on the same side group, and its structure is generally composed of the alkenyl part of the alkenyl monomer with polymerization reaction activity and endows the characteristic of neutral zwitterionization.
The side base part of the composition
.

Common ones are: carboxybetaine type (carboxylactone) polymer and sulfobetaine type (sultone) polymer

Amphoteric polymer flocculant has good water solubility, high molecular weight and good viscous capacity
.

Under different media conditions, the types of ions may be different, which is suitable for treating pollutants with different charges

Amphoteric polymers used as flocculants can not only remove suspended solids and colloids in wastewater, but also remove the range of general flocculants.
Dissolved substances in wastewater (such as colored substances, humic acids and surfactants, etc.
)
.

This is because the anionic and cationic groups in the amphoteric polymer can complex (integrate) with chromatic substances, humic acids, surfactants and other substances, and then achieve the purpose of removal through flocculation and precipitation
