Superabsorbent Polymers as a Soil Amendment for Increasing

Polymers are applied to build up the soil¡¯s capacity to absorb water. Polymers are primed by grafting and crosslinking of polyacrylamide (water-absorbent polymers) onto carboxymethyl cellulose (cellulose derivative backbone polymer chain). They are biodegradable and environmentally friendly .

Use of polymers and biopolymers for water retaining and soil

Polyacrylamide is a long-chain synthetic polymer that acts as a strengthening agent, binding soil particle together and holding soils in place, but Polyacrylamide alone not remediate poor soil structure [ 5 ]. Acid ¨C hydrolyzed Cellulose micro fibrils alternative to Polyacryalamide for soil stabilization was tested and show promises [ 6 ].

Effects of Polyacrylamide-Based Super Absorbent Polymer

Green approaches are much more appreciable during the present scenario. Soil amendments are frequently applied for improving water use efficiency, reducing soil salinity in arid and semi-arid areas, controlling the secondary salinization of cultivated soils, and increasing the carbon sequestration capacity of soils. Thus, lab soil column simulation experiments and field experiments were ...

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Effects of Polyacrylamide-Based Super Absorbent Polymer

SAP is a type of polymers with strong water-absorbing capability, and is composed of a large number of hydrophilic functional groups, such as carbonyls, hydroxyls, and quaternary ammonium salts [13¨C16]. It is capable of repeatedly and rapidly absorbing water, and retain hundreds of times its weight in water.

Spotlight on the Life Cycle of Acrylamide-Based Polymers

Water-soluble polymers have been studied for a long time regarding toxicity, the most used worldwide being the polyacrylamide. McCollister, in 1965, established the safety of polyacrylamides in the public health aspect for many applications wherein small amounts may possibly occur in the food or drink of animals or human subjects [ 116 ].
