Globally, water pollution is a crucial environmental issue. Research has indicated the presence of chemicals in aquatic environment, which includes dyes, antibiotics, and insecticides. Presently, there are numerous techniques available for degradation dyes include physicochemical, chemical, biological, electrochemical, membrane technologies along with sustainable such as photocatalysis. The remarkable photocatalytic activity graphene oxide nanocomposites one its most notable features. Graphene oxide's ability outperforms many traditional techniques, offering quick efficient way to remove dye. detailed mechanism induced materials organic was highlighted present study. Also, current integration plant sources their usage photocatalysts discussed. study could provide nominal insight on trends graphene-based bioremediation efficacy pollutant removal system.

The presence of 17-β-estradiol sulfate residue in water is great concern due to its hazardous nature (endocrine disruptor and carcinogen). For this, chitosan was used with graphene oxide prepare nanocomposite. This material characterized as an adsorbent for the removal water. showed a rapid, efficient, environmentally friendly method from optimal conditions maximum were 93.6% (4.68 mg/g) 2500 µg/L sulfate, 30 min agitation, 0.50 g/L nanocomposite, pH 7.0, temperature 25 °C. thermodynamic parameters confirmed spontaneity exothermic uptake process. kinetic study revealed first-order reaction, mechanism attributed liquid film diffusion. supra-molecular interaction between β-estradiol nanocomposite elucidated, highlighting pivotal role two hydrogen bonds binding affinities −6.80 −7.03 kcal/mole first second bonds. speedy, efficacy, friendly; making it applicable diverse systems.
