It indicated that for the oriented oxidation of all alkanes, the high coefficient of relative reactivity for petroleum was the key for the transfer of OH from oxidizing SOM to oxidizing alkanes.This study based on the freshwater algae Spiny scenedesmus (S. selleck kinase inhibitor scenedesmus) with tolerance to venlafaxine aiming to investigate algae removal abilities. Here presented for the first time to evaluate the effect of β-cyclodextrin (β-CD) on reduce toxicity and enhance removal ability of venlafaxine and O-desmethylvenlafaxine to S. scenedesmus. Based on dose-response results, the toxicity of R-venlafaxine (EC50 = 6.81 mg·L -1) and R-O-desmethylvenlafaxine (EC50 = 3.36 mg·L -1) to algae were more than two times than those in the presence of β-CD treatment (10.64 mg L -1 for R-venlafaxine and 11.87 mg L -1 for R-O-desmethylvenlafaxine). The significant differences were observed between S-venlafaxine (11.07 mg L -1) and S-O-desmethylvenlafaxine (10.24 mg L -1), which were more toxic than R-forms. The half-lives of R- and S-venlafaxine were 0.8 d and 0.5 d in the presence of β-CD, which were obvious shorter than those in alone treatments. In addition, our experiments not only demonstrated that β-CD performed particularly well for removal of venlafaxine and O-desmethylvenlafaxine, it significantly reduces the toxicity of venlafaxine to alga. These results highlight advantages of β-CD relevant to chiral drugs removal and protection of aquatic organisms, which may have a better application for environmental and ecological safety in future.Perfluorooctanoic acid (PFOA), a widely used compound, is harmful to the environment and human health. In this study, a facile one pot solvothermal method of integrating BiOCl with Zn-Al hydrotalcite to form spherical-shaped BiOCl/Zn-Al hydrotalcite (B-BHZA) sample is reported. The characteristics and main factors affecting photocatalytic PFOA and photocatalytic mechanism of BiOCl/Zn-Al hydrotalcite (B-BHZA) are systematically investigated. It is found that spherical-shaped B-BHZA possesses abundant defects and a larger surface area of 64.4 m2 g-1. The factors affecting photocatalytic removal PFOA (e.g., time, pH, initial concentration and dosage) are investigated by modeling the 3D surface response. The removal rate of PFOA is over 90 % in 6 h under UV light at an optimal pH of 2, an initial concentration of 500 μg/L and a dose of dosage 0.5 g/L. The main mechanism occurs by photo-generated h+ oxidation and synergistic effects from the photocatalysis process. Though investigating the intermediates of PFOA degradation and F-, a possibility was proposed that h+ initiated the rapidly decarboxylation of PFOA. The unstable perfluoroheptyl group is formatted and further conversed to short chain perfluorocarboxylic acid. This study provides a new insight for the preparation of highly efficient photocatalysts to the treatment of halogenated compounds in UV system.The stackable carbon fiber-based flow-through systems (m(nC + 1A)) were constructed, where the multi-cathode units (nC + 1A) were equipped with multiple cathodes (nC) and a counter anode (1A), and the m was the stackable numbers of the nC + 1A units. The configuration of the m(nC + 1A) systems with m and n values from 1 to 6 was optimized by comparing their disinfection performance toward a model pathogen (Escherichia coli) from the aspects of disinfection ability, energy consumption and HRT. For multi-cathode units (nC + 1A), increasing the cathode numbers (n) promoted the E. coli inactivation by the predominant direct oxidation on the anode. Among the stackable m(nC + 1A) modules, the 3(3C + 1A) module was recommended as the best configuration. In the stackable 3(3C + 1A) module with consecutive reduction-oxidation processes, the E. coli inactivation mechanisms were attributed to the direct oxidation on the anodes and H2O2-induced indirect oxidation on the cathodes. The synergistic effect between the stackable 3C + 1A units promoted the electro-redox of the electrodes and their disinfection ability, which was also accompanied by the enhancement of energy consumption for O2/H2O2 mutual transformation on the electrodes. In turn, the modules with excessive stackable unit numbers (m > 3) over-promoted the competitive reaction of O2/H2O2 mutual transformation, restraining the disinfection performance.Utilization of the coatings with self-healing anti-corrosion activities is one of the most promising routes for the development of advanced anti-corrosion coatings. In the present work, the green/sustainable corrosion inhibitive compounds based on the cerium acetylacetonate (CeA) was loaded into a beta-cyclodextrin (β-CD) nano-container (with negligible hazardous impacts) and through combined computer modeling and experimental approaches, the host-guest interactions/desorptions of the inclusion complexes of CeA with beta-cyclodextrin (β-CD) were assessed. The inhibition performance of the β-CD-CeA inclusion complex was investigated by electrochemical and surface experiments in a saline solution (NaCl, 3.5 wt.%). The particles were analyzed by Raman, XRD, FT-IR, and UV-vis spectroscopies. Additionally, the thermal properties in the 30-600 °C temperature range were examined by employing TGA/DTG test, and via the ICP analysis, the concentration of the released inorganic compounds in the electrolyte was studied. Achievements demonstrated 24 ppm Ce element existence after introducing β-CD-CeA inclusion complexes (during 24 h) in NaCl 3.5 wt.% solution. The analysis of Tafel curves proved that the prepared β-CD-CeA inclusion complex could inhibit the metallic substrate corrosion following the mixed cathodic and anodic mechanisms. The EIS investigation disclosed about 82 % inhibition degree after 48 h of metal immersion in the solution containing β-CD-CeA extract. The EIS analysis clarified that the silane coating (SC) resistance was enhanced noticeably by introducing the β-CD-CeA particles into the SC matrix. Using detailed-level (i.e., electronic and atomic) computer modeling techniques applying density functional theory (DFT), Mote Carlo (MC) and molecular dynamics (MD), the active sites, and the adsorption propensity of CeA complexes over the steel-based metallic adsorbents were explored. These modelings evidenced the CeA complexes interfacial adsorption on the steel.
