Radiation Synthesis of Green Nanoarchitectonics of Guar Gum-Pectin/Polyacrylamide/Zinc Oxide Superabsorbent Hydrogel for Sustainable Agriculture

Abstract In the current study, performance of superabsorbent hydrogel composites comprised Guar gum-Pectin/Polyacrylamide/ZnO crosslinked with gamma irradiation (10 kGy) has been investigated for sustainable agriculture. The claimed (GG/PC/PAAm/ZnO x ) were characterized by FTIR, TGA, and AFM. swelling capacity data reveal that equilibrium water (EW) was increased increasing ZnO content from 600 to 1050 g/g zero highest concentration ZnO, respectively. Furthermore, physical properties soil mixed hydrogels improved; holding (WHC) 66% retention (WR) kept at 15% after 20 days. showed a good degradability in biodegradation test. They also portrayed super-absorption three swelling/deswelling cycles. This advancement is important reducing consumption through irrigation arid lands. prepared proved as excellent candidates agriculture applications.
