In order to reduce water contaminants, like toxic metals and organic dyes, researchers are exploring different techniques, such as adsorption, photocatalytic degradation, and electrolysis. Novel materials are also being sought. In particular, biopolymers like guar gum and xanthan gum, that are eco-friendly, non-toxic, reusable, abundant and cost-effective, have enormous potential. Gum-based nanocomposites can be prepared and used for removing heavy metals and colored dyes by adsorption and degradation, respectively. This review explains the significance of gum-based nanomaterials in waste water treatment, including preparative steps, characterization techniques, kinetics models, and the degradation and adsorption mechanisms involved.202879648engAdsorptionDegradationGuar gumGum-based nanomaterialsWaste water treatmentXanthan gumEnvironmental ChemistryPollutionHealth, Toxicology and MutagenesisSDG 6 - Clean Water and Sanitationreview10.1007/s11356-023-29389-6https://www.scopus.com/pages/publications/85169904208
