polyacrylamide degradation and its implications

Polyacrylamide degradation and its implications

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. 1,...

Water Soluble Polymer Flocculants: Synthesis

Because of the low critical free adsorption energy of polymer chains on the particle surfaces, in the order of about 0.3 kT per segment, 6 the rate of polymer adsorption equals the rate of polymer loss from the solution, which explains the significant role of mixing in flocculation.

polyacrylamide

Polyacrylamide

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.

The authors found that PAM remained stable at the original application depth even 10 months after application and with 720 mm of additional water application. Sojka et al. reported, that due to its high sorptive ability and low mobility, high molecular weight PAM does not move more than a few centimetres from its point of entry into the soil.

Effect of Polyacrylamide Application on Runoff, Erosion,

A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m ?2) and molecular weights (12 and 18 Mg mol ?1) on runoff, soil erosion, and soil nutrient loss at a slope of 5¡ã. The results showed the two

Nutrient retention by different substrates from an improved

It is important to screen and determine appropriate substrate materials that can improve nutrient retention from LID practices. Soil amendment can be included, such as anionic polyacrylamide (PAM), which usually causes high levels of physical effects from a very small amount of material (Laird, 1997; Lentz et al., 2001; Sojka et al., 2007).

Effects of soil and water properties on anionic

Knowing the sorptive behavior of anionic polyacrylamide (PAM) by soils is useful in predicting the appropriate application rate, depth of effective treatment, and its mobility in soils, Sorption isotherms of PAM by soil materials, six natural soils, and their subsamples with partial organic matter (OM) removed by H 2 O 2 oxidization under different dissolved salt concentrations were examined
