Transfer and degradation of polyacrylamide-based flocculants

Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.

ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Fabricating an anionic polyacrylamide (APAM) with an anionic

Flocculation experimental results demonstrated that the anionic microblocks in the template copolymer could enhance the charge neutralization and bridging ability, and therefore an excellent flocculation performance of treating high turbidity water was observed. 1. Introduction

A method for measuring the degree of anionicity

A simple procedure was described for routine measurements of the degree of anionicity of polyacrylamide-based flocculants. The method relies on determining the total organic carbon content and assaying ion concentrations in a dilute solution (in distilled water at natural pH) of the tested flocculant. While the total carbon content in solution

biodegradation of polyacrylamide and its derivatives

Biodegradation of Polyacrylamide and Its Derivatives

Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 ¡Á 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
