What is anionic polyacrylamide?

This document provides safety information for anionic polyacrylamide. It is a white powder used as a flocculant in mineral processing and water treatment. The powder is non-irritating to skin but can cause eye and lung irritation if dust is inhaled.

Is anionic polyacrylmide a risk to the natural environment?

s not constitute a risk to the natural environment. Another review of polyelectrolytes by Environment Agency of the United Kingdom concluded that anionic polyacrylmide, like the other organic polyelectrolytes, is not a priority for the setting of environmental quality n.Physico-chemical p

How is polyacrylamide packed?

Keep containers closed when not in use. Polyacrylamide is packed in inner plastic bags and furtherly in polypropylene woven bags, with each bag containing 25kg. Liquid Polyacrylamide is packed in PE plastic drum and our company will provides special tanks for transportation and storage for the liquid product to the users.

Does FLOERGER polyacrylamide have residual acrylamide?

he finished polymer, especially in powder products. Quality assurance guarantees that all Floerger polyacrylamides contain less than 0.1% w/w (< 1000 ppm) of residual acrylamide monomer and less tha 0.5% w/w (< 5000 ppm) of residual sodium acrylate. In fact, on average, there is about 0.04% (400 ppm) of residual acrylamide and

Can a polyacrylamide oligomer be biodegraded?

ers, it becomes bioavailable and is biomineralized.A study using C14 labelling, designed to evaluate the potential to biodegrade anionic polyacrylamide demonstrated that a combination of photolysis and microbial at ack leads to natural attenuation of these polymers. After 48 hours of exposure to UV, the oligomer

Can acrylamide polymers be biodegraded?

ligomers, which are accessible to microbial attack. A recent study financed by SNF-Floerger, has demonstrated that photolysis followed by aerobic or anaerobic treatment esulted in efficient mineralization of the polymer. This study provides evidence that acrylamide polymers have the potential to be naturally broken down and biodegraded
