a role of flocculant chain flexibility in flocculation of sale
the intrinsic viscosity of polyacrylamide-based flocculants is a strong function of the degree of anionicity of the polymers. as the number of acrylic units increases along the polymer chain, the polymers gradually assume a more extended conformation in solution characterized by increasing intrinsic viscosity.
flocculants mining technology,as nasaco specialises in the mining industry it has built its flocculant range based on 20 years experience in the field and offers a range of products in the following categories: nasfloc 1000 series: non-ionic powder flocculants; nasfloc 2000 series: anionic powder flocculants; nasfloc 3000 series: cationic powder flocculants
- What is a polyacrylamide (PAM)?
- 1. Introduction Polyacrylamides (PAM) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. Their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety ( Abidin et al., 2012; Acharya et al., 2010 ).
- Does anionic polyacrylamide improve coagulation-flocculation process?
- Use of anionic polyacrylamide as a coagulant to improve the coagulation-flocculation process. High molecular weight hydrolyzed polyacrylamide.
- Does Pam solvated with Fe 3+ release acrylamide?
- It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (0.02 mg/L) under alkaline (7.5–8.5) conditions.
- Can high molecular weight Pam be used for degradation?
- This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
