In Part I, we outlined the importance of sustainable sonochemical treatment to intensify oil sands process affected water (OSPW) treatment empirically and hypothesized degradation pathways. Herein, we elucidate the formation of intermediate products with well-defined molecular level solutions. Proposed mechanisms describe hydroxylation, decarboxyla...

Propelled by enormous increase in demand for fuel sources, Canadian oil sands are becoming increasingly important as a fuel source due to their abundance and upgrading capability. However, extraction of bitumen, a high acid crude (HAC) oil, requires 2-3 units of water per unit of oil resulting in naphthenic acid (NA)-rich oil sands process affected...

... Advanced oxidation processes (AOPs), such as sonocatalysis, photocatalysis, sonophotocatalysis, ozonation, and Fenton and photo-Fenton reactions, are promising techniques owing to their high removal efficiency, biocompatibility, cost effectiveness, production of non-toxic compounds, and possibility of allowing reactions at ambient pressure and temperature [10][11][12]. During sonication, ultrasound (US) waves passing from an aqueous media can cause the breakage of chemical bonds and consequent free radical production [13][14][15]. The use of US alone to obtain a high removal efficiency for organic contaminants usually requires a large amount of energy owing to the considerable energy loss during this process. ...
... More complex cyclic hydrocarbons undergo hydroxylation and degradation. The mechanism is critical for unit operation design [3]. Shende et al. targeted perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). ...
