Polyacrylamide in Agriculture and Environmental Land
Using anionic PAMs of 10–15 Mg mol −1, Lu and Wu (2003a) found that PAM penetration depth was about one‐eighth to one‐half of the water penetration depth, with a particularly high PAM retention in the top few centimeters of the soil. The PAM retained in the top 0–2 mm of soil ranged from 16% to 95% of the total applied.

Treatment of polyacrylamide production wastewater by
Using this technique, a PAM wastewater treatment plant with a processing capacity of 600 m 3 ·d −1 was implemented and has been stably operated for nearly 18 months. Compared to the pervious process, the HRT decreased 50% and the COD, NH 4 -N and T-N removal efficiency increased to 93%, 92% and 67–80%, respectively.

A new insight into PAM/graphene-based adsorption of water
Graphene materials have been extensively verified as a good adsorbent for tackling wastewater containing various aromatic pollutants; however, little attention has been paid to understanding the graphene-based adsorption mechanism. Here, a systematic work is performed to prepare a series of graphene oxide (GO)-incorporated polyacrylamide hydrogels, with a three-dimensional (3D) monolithic

A Review of the Application of Biopolymers on Geotechnical
2.1.4. Polyacrylamide. Polyacrylamide (PAM) is a water-soluble polymer, and Figure 5 shows the structure unit of PAM polymer. PAM is widely used for EOR, water treatment, and soil amendment effects because PAM is more effective and relatively inexpensive [36–38].

Treatment of the soil surface with 5020 kg ha-1 of anionic PAM increased the final infiltration rate of soils exposed to rain by an order of magnitude and reduced runoff and interrill erosion by several-fold. Laboratory studies demonstrated that no rill ero-sion occurred in PAM solutions that contained 2.5, 5.0, and 10.0 g PAM m- 3 (per unit of
