anionic polyacrylamide cationic anionic polyacrylamide
no studies on the environmental fate of anionic polyacrylamide are available. as a high-molecular-weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate (lyons and vasconcellos, 1997). the environmental fate of anionic polyacrylamide will be determined primarily by adsorption (lyons and vasconcellos, 1997).
fabricating an anionic polyacrylamide (apam) with an anionic,abstract. ultraviolet (uv)-initiated template polymerization (utp) was used as a feasible strategy to prepare a novel anionic polyacrylamide (apam) with a microblock structure. in the template copolymerization system, acrylamide and sodium allylsulfonate (sas) were used as monomers, and poly (allylammonium chloride) (paac) as a template
degradation of polyacrylamide and its significance in nature
the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning.

acute and long-term effects of anionic polyacrylamide apam
in eor processes polymers will follow the produced water fraction during oil production and can thereby enter the environment with produced water discharges. eor polymers, including apam, are generally assumed to be relatively nontoxic (biesinger and stokes, 1986; bolto and gregory, 2007). however, data on impacts on aquatic species, especially

chemical polyacrylamide water treatment polymer
polyacrylamide (abbreviated as pam or paam) is a polymer with the formula (-ch 2 chconh 2 -). it has a linear-chain structure. pam is highly water-absorbent, forming a soft gel when hydrated. in 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.

use and notice of nonionic polyacrylamide iro oil drilling
use and notice of nonionic polyacrylamide. polyacrylamide is mainly cationic, anionic and non-ionic. among these types, the application range of nonionic polyacrylamide is limited. the production volume and model of the manufacturer are also relatively small. the nonionic polyacrylamide is a good flocculant in water treatment.

- Which cationic polymer has the best flocculation efficiency?
- The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
- What is the molecular weight of paetac flocculant?
- The synthesized flocculants are cationic and highly charged with a viscosity average molecular weight of 340 – 560 KDa and 180 – 190 KDa. The high molecular weight of PAETAC provided better flocculation efficiency for both microalgal species.
- What is nonionic powder flocculants / polyacrylamides (ndpam)?
- Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.
- Can a high charge polymer ensure high flocculation efficiency of microalgae?
- The three PolyDADMAC have a similar charge with zeta potential values of 12.3, 11.9 and 12.9 mV for very low, medium, and high molecular weights. This study, therefore, suggests that new polymer synthesis could aim to achieve a molecular weight of highly charge polymer at above 350 KDa to ensure high flocculation efficiency of microalgae.
