The importance of water for all living organisms is unquestionable and protecting its sources is crucial. 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.
水对所有生物的重要性是毋庸置疑的，保护其水源至关重要。为了减少水中的污染物，如有毒金属和有机染料，研究人员正在探索不同的技术，如吸附、光催化降解和电解。新型材料也在被寻找。特别是像瓜尔胶和黄原胶这样的生物聚合物，它们环保、无毒、可重复使用、丰富且具有成本效益，具有巨大的潜力。可以制备基于胶的纳米复合材料，并分别通过吸附和降解用于去除重金属和有色染料。本综述解释了基于胶的纳米材料在废水处理中的重要性，包括制备步骤、表征技术、动力学模型以及涉及的降解和吸附机制。
