aggregate stability as affected by polyacrylamide

Aggregate Stability as Affected by Polyacrylamide

The favorable effects of the environmentally friendly, nontoxic, anionic polyacrylamide (PAM) as a soil conditioner have long been established. Some uncertainties exist, however, regarding the effects of PAM molecular weight (MW) on its performance as a soil amendment and its ability to penetrate into aggregates and stabilize interior surfaces.

Effect of Polyacrylamide Application on Runoff, Erosion

Soil erosion affects soil productivity and environmental quality. 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°.

The viscosity of a polymer in solution is a function of its molecular weight, where viscosity increases with increasing chain length. High-viscosity hydraulic fracturing depends on fast-hydrating guars (FHGs) so fluid viscosity can be quickly and precisely timed.

Minerals | Free Full-Text | Review on Beneficiation

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.

Specific UV absorbance (SUVA) is defined as the UV absorbance of a water sample at a given wavelength normalized for dissolved organic carbon (DOC) concentration. Our data indicate that SUVA, determined at 254 nm, is strongly correlated with percent aromaticity as determined by 13C NMR for 13 organic matter isolates obtained from a variety of aquatic environments.
