Why are non ionic and anionic polyacrylamide based flocculant chains used in tailings treatment?

Non-ionic and anionic polyacrylamide (PAM)-based flocculant chains are commonly employed in a vast majority of tailings treatment operations and several studies have been conducted on degradation of PAMs due to various factors such as pH, light and temperature , microbial degradation and chemical degradation .

Does ultrasonication affect the degradation of polyacrylamide-based flocculants?

The effect of ultrasonication, screening and shearing on five polyacrylamide-based flocculants of similar molecular weight but different degrees of anionicity (DA) was studied through measurement of intrinsic viscosity ( [η]) and size exclusion chromatography (SEC) to investigate the influence of DA on the degradation of polymers.

Is Pam a water soluble polymer?

The polyacrylamide flocculant (PAM) is a linear water-soluble polymer and is one of the most widely used types of water-soluble polymers. PAM and its derivatives can be used as efficient flocculants, …

What is high molecular weight polyacrylamide (PAM)?

Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.

Can cationic polyacrylamide flocculants be used in river water?

The amount of flocculant added is 1/50 of that of inorganic flocculants, but the effect is several times higher than that of inorganic flocculants. For river water with severe organic pollution, it is better to use inorganic flocculants in conjunction with cationic polyacrylamide flocculants.

Is Pac-P a hydrophobic polymer?

In this study, a novel inorganic-organic hybrid polymer flocculant PAC-P (AM-BA) with hydrophobic groups was synthesized using the aqueous solution free radical micelle polymerization method. The raw materials used were polyaluminum chloride (PAC), polyacrylamide (AM), and butadiene acetate (BA).
