The treatment of oily wastewater has become a serious environmental challenge, for which graphene oxide emerged as promising material in solving the problem. ever-growing utilization (GO) necessitates constant review. This review article employs comprehensive literature survey methodology, systematically examining peer-reviewed articles, focusing on, but not entirely limited to, last five years. Major databases such EBSCOhost, Scopus, ScienceDirect, Web Science and Google Scholar were searched using specific keywords related to GO treatment. inclusion criteria focused on studies that specifically address application, efficiency, mechanisms treating wastewater. data extracted from these sources then synthesized highlight most important developments, challenges, prospects this field. As far is concerned, majority revolve around use mitigating fouling membrane processes, improving stability, capacity reusability sorbents, enhancing photodegradation by minimizing charge recombination.

Response surface methodology (RSM) and Box–Behnken (BB) statistical experiment design were developed to study the optimization of oily wastewater treatment using Sargassum latifolium. The characterization latifolium was studied fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), N2 adsorption/ desorption, Raman techniques. These studies demonstrated importance various functional groups such as carbonyl, amino, carboxyl, hydroxyl on adsorption mechanism. specific area S. 111.65m2/ g. Scanning (SEM) showed that interaction with oil led development flake-like deposits its surface, causing become uneven. Four process-independent parameters, including contact time, volume, adsorbent dosage, pH optimized for best response crude design. output summarized an additional ANOVA analysis. Optimization conditions onto Latifolium found be at dose 0.13g, volume 24.29ml, time 57.44 minutes, initial 9.54. Langmuir Freundlich isotherm models used apply equilibrium results suggest model better fits experimental data compared model. capacity 45.87gm under ideal conditions, which somewhat lower than RSM model's value 46.14gm.

The global challenge of oil spill treatment has been addressed using nanocomposite-based natural fibers. These materials offer great potential in cleanup and are considered due to their environmental friendliness, high efficiency, low cost. Thus, the current study reports a novel composite fabricated from date palm fiber (DPF) recycled polyethylene terephthalate (rPET) with proper combination mixture carbon nanotubes (CNTs) graphene nanosheets (GNSs) for removal. established nanocomposite (DPF-rPET/CNT/GNS) was via physical mixing various quantities (0.9, 0.8, 0.7 g) PET, along varying loads DPF at different proportions CNT:GNS. prepared fully characterized scanning electron microscopy–energy dispersive X-ray (SEM-EDX) analysis, transmission microscopy (TEM), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) analysis. In static experiments under optimal parameters pH, sorbent doze, shaking time, quantity diesel oil), (DPF-rPET/CNT-GNS nanocomposite) displayed excellent adsorption capacity (98 mg/g). This also expands utility reusability adsorption, maintaining performance after five cycles. data fitted well Langmuir isotherm model correlation coefficient (R2) 0.99 maximum 99.7 mg/g, indicating monolayer adsorption. Additionally, kinetics followed pseudo-second-order model, an R2 near unity 99.09 mg/g. highlights promising DPF-rPET/CNT-GNS as effective adsorbent treating oily water.
