The human population has massively increased throughout the world. This has created various serious challenges, especially water pollution issues. Heavy metals, dyes, textile industries, microorganisms, organic and chemical pollutants can be included as main sources of water pollution. There are various methods for contaminant disposal. In this regard, the adsorption technique can be considered the most common method. In this technique, alum and polyaluminum chloride are widely used chemicals. However, they have harmful side effects on the environment, due to their chemical nature. One of the best solutions to overcome this issue is the use of natural materials and polysaccharides, which are abundant materials, biocompatible, biodegradable, non-toxic and functional groups with low processing costs. These materials include Guar Gum (GG), derivatives such as Al2O3 (GG-AO), GG nanocomposites, acrylic gum-based hydrogels, GG-hydrogel, gum nano-hydrogels, magnetic nano-GG, agaric GG, itaconic (Aldehyde GG), Galacyl-Hydrazine modified GG (GG-GH), depolymerized GG (oxidized GG), Guar-Graft Poly(Methylacrylate) (GG-g PMA), poly(acrylamide) GG-silica nanocomposites, GG Sulphonic Acid (g-GG/SiO2), GG Nitrilotriacetic Acid (GNTA) resin, etc. Different factors such as pH, adsorbent amount and contact retention time have significant impacts on adsorbent efficiency. Various studies have reported that pH values of 4–8 resulted in efficiency higher than 90%. The concentration of the adsorbent and the contact time are varied, depending on the type of the considered derivative. The use of GG and its derivatives can be an effective strategy to greatly reduce the cost of water treatment. In addition to being cost-effective, the proposed strategy is biocompatible and eco-friendly.
