Polyacrylamide in Agriculture and Environmental Land
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 in runoff.

Salt-Tolerant Superabsorbent Polymer with High Capacity
The application of superabsorbent polymers (SAPs) is hindered because their absorption capability is greatly affected by the electrolytes in a solution. A novel modified water-absorbent polymer was fabricated by solution polymerization of sulfamic acid-modified starch and acrylic acid; the swelling ratios of this absorbent polymer were 1026 g/g in deionized water and 145 g/g in 0.9% sodium

Silver recovery aqueous techniques from diverse sources
Since it has become of great concern to recover and remove monovalent silver ions (Ag +) from industrial effluents and spent sources, up to ppm level (De Radigues et al., 2010). Moreover, a great interest in silver recovery for both environmental toxicity and economic point of view ( Lee et al., 2005 , Park and Fray, 2009 ).
