Abstract:
Hydrogels are 3- dimensional polymeric network structures that can absorb a large amount of water. The hydrogels possess re
markable hydrophilic characteristics, biocompatibility, and a high swelling ratio making them versatile in various applications.
Guar gum biopolymer derived from guar beans showed hydrogel characteristics and can be modified by derivatization, copoly
merization, crosslinking, and composite formation. Superabsorbent hydrogels made from guar gum have numerous applications
across various industries such as agriculture for water retention in soil, drug delivery carriers, metal ion removal sorbents, dye
adsorbents, environmental applications, and wastewater treatment. Dye plays an important role in water pollution. Various
methods reported to remove dyes from waste water but among all the method adsorption is the best method. The use of guar
gum- based superabsorbent hydrogels not only reduces waste but also promotes the development of ecofriendly and resource-
efficient materials. This review mainly focuses on the properties of guar gum biopolymer, its modifications and its employability
in various separation and enrichment techniques.
