Toxicity of Anionic Polyacrylamide Formulations when Used for Erosion Control in Agriculture
In one conservation practice, a high molecular weight, anionic polyacrylamide (PAM) is applied to advancing furrow stream flows at a concentration of 10 mg L. Because PAM stabilizes furrow soil

Anionic polyacrylamide influence on the lead(II) ion accumulation in soil – the study on montmorillonite
Purpose Polymeric substances, as soil conditioners, limit the erosion process as well as improve the soil structure. The same macromolecular compounds may influence the heavy metal accumulation in soil environment. The main aim of this study was
in Fig. 2a.Six characteristic peaks of Fe 3 O 4 cubic space group (d-spacing = 2.96, 2.52, 2.09, 1.71, 1.61 and 1.48 Å) were observed, which, based on the standard pattern for Fe 3 O 4, showed that the prepared samples were of high purity.
Anionic polyacrylamide as a substance strengthening the Pb(II) immobilization on the kaolinite surface
Moreover, the influence of commonly used soil flocculant—anionic polyacrylamide (AN PAM), on the lead sorption on the kaolinite surface, was investigated. Potentiometric titration method and electrophoretic mobility measurements allowed
Soil organic carbon (SOC) is one of the most critical factors determining soil quality or fertility. Recent survey has reported the severe degradation of SOC by soil erosion in agricultural fields throughout the world. To maintain soil quality

Turbidimetric Determination of Anionic Polyacrylamide in Low Carbon Soil Extracts - ResearchGate
Polyacrylamide is one possible organic agent, which has been shown to influence the shear strength, stiffness, soil remediation, and erosion resistance of geomaterials.
Anionic polyacrylamide APAM for water tank cleaning chemical This product is a water- soluble high polymer.It's not soluble in most organic solvents, with good flocculating activity, and can reduce the friction resistance between liquid.
- Can acrylamide be used to make a hybrid flocculant?
- The main conclusions from this work are: 1. A new kind of hybrid flocculant—HAPAM—has been prepared by polymerization of acrylamide in Al (OH) 3 colloidal solution. Ionic bonds between Al (OH) 3 colloid particles and polyacrylamide chains in HAPAM are displayed.
- Why is the flocculation efficiency of h-3a low?
- The flocculation efficiency ( Arel) of the H-3A sample decreased by more than 50% due to destruction of the Al (OH) 3 core. In this case H-3A was like the pure PAM, in which only weak adsorption or bridging action exists. Therefore, the flocculation efficiency of H-3A and PAM is low and the floccules formed are loose.
- How is Al(OH) 3 colloidal solution prepared?
- Al (OH) 3 colloidal solution was prepared by slowly dropping 110 ml of 15 wt% aqueous ammonium carbonate into 190 ml of 8 wt% aqueous aluminum chloride under strong stirring at room temperature.
