superabsorbent hydrogels based to polyacrylamide/cashew tree

Superabsorbent Hydrogels Based to Polyacrylamide/Cashew Tree

PAM is a conventional hydrophilic polymeric substance that is used to obtain SAHs, mainly for application as soil conditioner [28,29]. Although PAM exhibits hydrogel formation capacity, chemical treatments, such as alkaline hydrolysis, have been suggested as a way to enhance the swelling of this synthetic polymer .

Superabsorbent polymers used for agricultural water retention

Due to super high water absorption and water retention capacity, superabsorbent polymers (SAPs) can be applied to effectively ameliorate utilization of water in agriculture, such as retaining moisture in the soil and reducing the irrigation water consumption [2, 3 ].

Superabsorbent Polymers: From long-established, microplastics

The cross-linked polyacrylates SAPs have the best absorption capacity while the polyacrylamide homopolymer and copolymer SAPs have better salt resistance performance for their non-ionic nature. Compared with acrylate-based SAPs, natural polymers-based SAPs have better biodegradability which are environment-friendly products.

Synthesis and characterization of highly elastic

This research developed a semi-IPN based on NR that can be practically used for industrial wastewater treatment. NR was incorporated in polyacrylamide (PAM) hydrogel to form a secondary polymer network via physical chain entanglement in order to improve the chemical stability, structural durability, and elasticity of the hydrogel.

Effects of superabsorbent polyacrylamide hydrogel and gypsum

Gypsum Highlights Synergistic effects of SPH and gypsum decreased the release of CP. Sole application of SPH augmented CP release from agricultural soils. Organic matter (OM), pH, and soil texture were regarded as major factors affecting CP release. Responsible editor: Zhaohui Wang Xinqiang Liang [email protected]

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 ...
