Carboxylated nanocellulose superabsorbent: Biodegradation and soil water retention properties

In this study, TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-oxidized nanocellulose superabsorbents are prepared using three different drying techniques: freeze-dried, and oven-dried at low high temperatures. The benefits investigated by evaluating the superabsorbent structure, composition application rate. absorption performance of is affected concentration type salts in soil water extracts. Oven-dried 50°C SAP presents highest ionic sensitivity attributed to its large number accessible carboxylate groups. retention treatments increases with increasing Soil treated freeze-dried shows retention, whereas those amended remain moist longest. biodegradation rate these materials depends on nutrient availability. Carboxylated emerge as high-performance biodegradable for agricultural use, able replace current non-biodegradable petrochemical-based superabsorbents.
