amphoteric polymers
The amphoteric polyacrylamide (PAM) produced by our Company under the trade name of LHPAM, is made from acrylic cationic monomer, acrylamide monomer and a hydrolyzing agent through a copolymerization process.Through infra-red sqectrum analysis, it is shown that the molecular chain of the product has not only carboxyl anionic charges resultion from the hydrolysis of acrylamide, but also

3, lowering resistance: PAM can effectively reduce fluid friction, the water can be added to trace PAM 50-80% reduction in resistance. 4, thickening: PAM have a thickening effect under neutral and acid conditions, when the PH value above 10 PAM easy hydrolysis. When semi-mesh structure, thickening more obvious. PAM usage instructions
Polyacrylamide (PAM) has been widely used as an efficient flocculant with bargain price and highly stable in wastewater treatment [35] [36][37]. This is possible to design high selectively non
Evaluation of the flocculation performance
In the present work, a novel amphoteric chemically bonded composite flocculant (carboxymethyl chitosan-graft-polyacrylamide, denoted as CMC-g-PAM) was successfully prepared and used to flocculate the kaolin suspension.The flocculation performance of CMC-g-PAM in acidic, neutral, and alkaline conditions was systematically evaluated by light scattering in combination with fractal theory, as well
Polyacrylamide and cationic polymer based flocculants used in wastewater and industrial effluent treatment are highly efficient at low doses. But they are fragile and expensive. On the other hand, polysaccharides are cheap, biodegradable, shear stable but less effective as flocculants ( Singh et al., 2003 , Singh et al., 2009 , Krishnamoorthi
Flocculant - an overview | ScienceDirect Topics
Amphoteric flocculants usually are prepared by amination of lignosulfonates. For example, the amphoteric flocculant can be prepared with lignosulfonate (or its silicone-modified product) and polyacrylamide [26].This flocculant can increase the retention of small fibers and fillers for papermaking, which improves the physical properties of paper.
A new modified hydrophobic organic polymer P(AM-DM-DMC12) is synthesized by free radical polymerization of three monomers in aqueous solution using a REDOX initiator system. Its structure is characterized by FT-IR and 1 H-NMR, the effect of reaction conditions on the product is studied, and the flocculation performance and mechanism are discussed with the aim of wastewater turbidity and COD
A review on application of flocculants in wastewater
In the current work, a series of amphoteric grafting chitosan-based flocculants (carboxymethyl chitosan-graft-polyacrylamide, denoted as CMC-g-PAM) was designed and prepared successfully. The flocculants were applied to eliminate various dyes from aqueous solutions.
In this study, a novel magnetic polyacrylamide (PAM) coagulant based on the core of magnetite (Fe 3 O 4), with oleic acid serving as modifier and acrylamide as monomer, was synthesized to remove suspended solids in kaolin-suspended water.The composites were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermo gravimetric analysis and scanning electron microscopy.
