“…It is well known that hydrocarbons, particularly MAHs, evaporate rapidly from WAFs [10,13]. There was good agreement between the nominal concentrations of MAHs and PAHs in the dilutions and the measured concentrations.…”

“…In an actual spill situation, the oil to water ratio is much lower than that used to prepare the WAFs (about 33:1), and the dissolved hydrocarbon concentration in the water decreases as the oil to water ratio decreases [13].

The evaporative weathering properties, chemical composition, and toxicity of three Australian Northwest Shelf crude oils and an Australian diesel fuel were evaluated. The crude oils include one each of a condensate, a light, and a medium crude oil. Between 23 and 100% of the mass of the oils is lost during evaporative weathering equivalent to about 1 week on the sea surface. During weathering, the oils lose most of their monocyclic aromatic hydrocarbons (MAHs) and phenols; concentrations increase of less volatile phenols and polycyclic aromatic hydrocarbons (PAHs). The acute toxicity of water‐accommodated fractions (WAFs) of the fresh and weathered oils to six species of temperate and tropical marine animals ranges from > 100% to about 11% WAF. The MAHs are the most important contributors to the acute toxicity of the WAFs of the fresh oils. The contribution of PAHs to WAF toxicity increases with weathering. About 58% of the hazard indices (HI: exposure concentration/acutely toxic concentration) for the WAFs of the two light oils weathered for the equivalent of 1 d are attributable to PAHs. The toxicity of the WAFs of the condensate and light crude oil can be accounted for by MAHs, PAHs, and phenols; WAFs of the middle‐weight crude oil and diesel fuel are higher than predicted based on their concentrations of total MAHs, PAHs, and phenols, indicating that other components of the WAFs are contributing to their toxicity. These components may include the unresolved complex mixture and polar compounds (resins).

“…Figure 9a shows that the separation efficiency of the TSW membrane decline slightly with the increase in the temperature of the oil-water mixture. This phenomenon could be attributed to the increase in solubility of the oil-water mixture when exposed to a higher temperature condition [55]. The experimental outcome shows that the separation efficiency at 40 o C only experiences a slight decrease from 99.90% to 99.87%.…”

“…This outcome could be attributed to the alteration in oil-in-water solubility,a si th as been reported that the solubility of oil increases with increasing temperature. [22] Nonetheless, the decrease in separation efficiency at 40 8Ci sn ot significant (from 99.89 %t o9 9.87 %), and this indicates that this membrane may be applied in different temperature media. Furthermore, NaCl solutions of various concentrations were added into the lubricant oil-in-water emulsion to investigate the separation efficiency of this membrane operating under different ionic conditions.…”

Globally, efficient oil-water separation for surfactant-stabilized oil-water emulsions has been in urgent demand. The current options available for separation are neither sustainable nor resistant to fouling. Herein, we introduce a hierarchically nanostructured TiO2/Fe2O3 composite membrane, which is capable of separating surfactant-stabilized oil-water emulsions with high separation efficiency. The high oil rejection rate is contributed by the acquisition of an interconnected delicate network and underwater superoleophobic interface. Meanwhile, its self-cleaning function promote the facile recovery of the contaminated membrane. Furthermore, the mechanical flexible characteristic of the TiO2/Fe2O3 composite membrane widens its applicability in industrial employment. Thanks to these properties, this novel membrane can be considered as a practical option for treating surfactant-stabilized oil-water emulsions.
