“…The salinity of the surface of the marine environment varies from a region to region, which is usually in the range of 3.3 to 3.7 wt %. Some ocean environments have higher or lower salinity because of the unique climate and hydrology conditions . In this study, a range of salinities was selected to test its impact on washing performance.…”

“…To avoid the impact of scavengers on oil removal in surface-washing processes, quenching experiments of reactive species were conducted by measuring the oil concentration in oil-in-water emulsions. The oil-in-water emulsion was prepared by vigorously stirring engine oil and UP water using a homogenizer (Ultra-Turrax T25, IKA, Germany) at 12,000 rpm for 30 min . Subsequently, a mixture containing an emulsion (15 mL), MoS 2 , and a scavenger was sealed in vials and shaken at 300 rpm and 20 °C for 24 h. Then, the oil in the mixture was extracted at 300 rpm and 20 °C for 24 h by adding the mixture (2 mL) and n -hexane (15 mL) in vials.…”

The gigantic petroleum exploration and production are threatening the lives and well-being of people and other species. Pizeocatalysis is a bridge to transfer ceaseless mechanical energy to chemical energy and thus triggers redox reactions. In this study, piezoelectric MoS2 was used as a surface-washing fluid to physically and chemically decontaminate oiled sands. The MoS2 displayed single- and few-layer structures, which were conducive to piezocatalysis. The addition of MoS2 could decrease the interfacial tension, thereby facilitating oil removal. The oil removal efficiency varied under different environmental conditions. Quenching experiments with different scavengers and electron paramagnetic resonance (EPR) spectra showed the existence of reactive oxygen species (ROS) including 1O2, •O2 –, and •OH. It was found that shaking was a necessary initiator to trigger piezocatalysis and singlet oxygen (1O2) was the dominant ROS. The MoS2 fluid exhibited good stability, maintaining high removal efficiency after five reuse cycles. Notably, results indicated that high-molecular-weight hydrocarbons were degraded into lower-molecular-weight ones, indicating the existence of chemical oxidation pathways in oil removal. This study provides a facile self-powered piezocatalytic surface-washing process by harnessing natural energy from water agitation to clean up oiled sands.

“…The frequency and magnitude of marine petroleum-derived product (PDP) spills have increased dramatically in recent years due to the combined effects of escalating population growth and industrial expansion [ 1 , 2 ]. The production, transportation, and consumption of petroleum-based products have increased in tandem with the rising global energy demand, which has amplified the likelihood of accidents and incidents along the supply chain [ 3 ].…”

The exponential increase in the production and transportation of petroleum-derived products observed in recent years has been driven by the escalating demand for energy, textiles, plastic-based materials, and other goods derived from petroleum. Consequently, there has been a corresponding rise in spills of these petroleum derivatives, particularly in water sources utilized for transportation or, occasionally, illegally utilized for tank cleaning or industrial equipment maintenance. Numerous researchers have proposed highly effective techniques for detecting these products, aiming to facilitate their cleanup or containment and thereby minimize environmental pollution. However, many of these techniques rely on the identification of individual compounds, which presents significant drawbacks, including complexity of handling, subjectivity, lengthy analysis times, infeasibility for in situ analysis, and high costs. In response, there has been a notable surge in the utilization of sensors or generalized profiling techniques serving as sensors to generate characteristic fingerprints of these products, thereby circumventing the aforementioned disadvantages. This review comprehensively examines the evolution of techniques employed for detecting petroleum-derived products in water samples, along with their associated advantages and disadvantages. Furthermore, the review examines current perspectives on methods for the removal and/or containment of these products from water sources, to minimize their environmental impact and the associated health repercussions on living organisms and ecosystems.
