One-pot preparation of lignin-based cationic flocculant and ... 簡

Lignin shows good potential as a flocculant material, but more complex reaction processes are often required to obtain products with high flocculation performance. In this work, kraft lignin, acrylamide, and 3-chloro-2-hydroxypropyltrimethylammonium chloride were used as materials to prepare lignin-based flocculants (CPKL) using a one-pot method.

Chapter 11: Dispersion, Coagulation and Flocculation

The flocculation process is opposite to dispersion. In a dispersed system, particles of all species can be aggregated into larger structures by several mechanisms. Aggregation, based on reducing inter-particle repulsion forces, is known as coagulation and the aggregates are called coagula.

Can polyacrylamide grafted hydroxypropyl methyl cellulose be used as flocculant?

Effect of flocculants for the treatment of mining industry wastewater. 4. Conclusion Based on the observed results, it can be concluded that polyacrylamide grafted hydroxypropyl methyl cellulose may be used as high performance flocculant for treatment of synthetic effluents and mine wastewater.

Is polyacrylamide water soluble?

Polyacrylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). Polyacrylamide PAM is currently the most widely used synthetic organic polymer flocculant, and sometimes it is also used as a coagulant aid.

What are flocculants made of?

In most cases, flocculants are polymers composed of polyacrylamide (PAM) (Taylor et al. 2002). PAM is a polymer with high molecular weight, synthetized from acrylamide (AMD) and acrylic acid/acrylate (AA) (Scott et al. 1996; Caulfield et al. 2002).

What is the raw material for the production of polyacrylamide?

The raw material for the production of polyacrylamide is polyacrylonitrile CH2=CHCN. Under certain conditions, acrylonitrile is hydrolysed to produce acrylamide, and acrylamide is then subjected to suspension polymerization to obtain polyacrylamide.

What is the temperature of polyacrylamide?

Their glass transition temperature is well above room temperature (> 400 K). Polyacrylamide PAM is currently the most widely used synthetic organic polymer flocculant, and sometimes it is also used as a coagulant aid. The raw material for the production of polyacrylamide is polyacrylonitrile CH2=CHCN.

Can a polymer be used as a flocculant?

To sum up, the use of a given organic polymer as flocculant or flocculant aid can only enhance adsorption affinity and flocculation efficiency for one certain type of particle, but not for others in the non-ballasted flocculation system , .
