Extraction and Characterization of Nanocellulose-Based Hydrogels for Water Conservation in Omani Agriculture

Abstract

This research project focuses on extracting and characterizing nanocellulose from agricultural waste for hydrogel production. The nanocellulose samples achieved a 98% purity through EDX analysis, and SEM, EDX, FTIR, and XRD tests confirmed their structural and compositional properties. Cross-linking the nanocellulose with Arabic gum and chitosan produced environmentally friendly hydrogels. Laboratory tests evaluating water absorption and retention determined that higher amounts of Chitosan resulted in longer absorption times, while 15% Chitosan with 30g exhibited the highest absorption capacity. Additionally, 15% Arabic Gum with 20g demonstrated rapid absorption within approximately 5 minutes, suggesting enhanced absorption properties. These findings contribute to sustainable agriculture in Oman, offering an innovative solution for water conservation. The results provide valuable insights for developing efficient hydrogel formulations and implementing water management strategies that promote environmental stewardship and facilitate water conservation in crop cultivation.
