environmental impurities. Analysis of PAM in oil sands tailings or oil sands process water is challenging for two main reasons: (1) the compounds vary widely in terms of chemical properties; and (2) they are highly adsorptive within a complex matrix of OSPW and tailings. PAM Degradation PAM is applied to tailings at all operating oil sand mines.

Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

The Sustainable Development Goals of the United Nations call for applying soil management practices that contribute land degradation neutrality. Our objectives were to investigate the effect of (i) soil management¡ªconventional tillage (CT under crop) and no-tillage (NT under grass)¡ªand (ii) an amendment (polyacrylamide (PAM)) application on the structure stability indices of soils from a

Effects of soil and water properties on anionic polyacrylamide Sorption

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

Using Polyacrylamide (PAM) to Reduce Erosion on Construction Sites

PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units. When linked in long chains, these units can be modified to result in a net positive, neutral, or negative charge on the PAM molecule. The positively charged, or cationic, PAMs, are not used for erosion control because they can be toxic to fish and
