Siderite-Driven Oxidative Degradation of TCE

Check if the same lab product or an alternative is used in the 5 most similar protocols

All chemicals used in this study were prepared using ultrapure (filtered, distilled) water (Millipore Model Milli-Q Academic A10). Siderite was purchased from the Wuhan Iron and Steel (Group) Corporation, China. Hydrogen peroxide (H₂O₂, ~30% solution), trichloroethene (TCE, >99% purity), sodium persulfate (Na₂S₂O₈, >98%), benzoic acid (>99.5%), p-hydroxybenzonic acid (>99.5%), and isopropanol (>99.7%) were obtained from the Beijing Chemical Plant. 5,5-Dimethyl-1-pyrroline N-oxide (DMPO, ≥97%) was purchased from Sigma-Aldrich, Inc.
The following reagent concentrations were used for all of the experiments. For TCE, 10 μL of pure TCE was added to each vial for the relevant experiments. This quantity is equivalent to 11.15 mmol/L (1,500 mg/L) in solution. This equivalent concentration exceeds the aqueous solubility of TCE, reflecting the presence of TCE liquid. Na₂S₂O₈: 6.3 mmol/L (1,500 mg/L), H₂O₂: 0.15 mol/L (5,100 mg/L), siderite: 11,450 mg/L. These oxidant concentrations are relatively low compared to typical concentrations used for field applications. Thus, these concentrations will produce conservative results.

All chemical stock solutions used in this study were prepared using ultrapure (filtered, distilled, deionized) water from a Millipore system (Millipore Model Milli-Q Academic A10). Siderite was obtained from the Wuhan Iron and Steel (Group) Corporation, China. Hydrogen peroxide (H₂O₂, ~30 wt. % in water), sodium persulfate (Na₂S₂O₈, >98%), trichloroethene (TCE, >99% purity), sodium phosphate monobasic (NaH₂PO₄, ≥99% purity), 1,2-dichloroethane (DCA, ~99.8% purity) were purchased from Beijing Chemical Works.
The following reagent concentrations were used for all of the experiments. Oxidant concentrations were selected based on the results of previous studies employing persulfate and H₂O₂ (Yan et al. 2013 , 2015 (link)). For TCE, 10 µL of pure TCE was added to each vial for the relevant experiments. This quantity is equivalent to 11.15 mM (1,500 mg/L) in solution. This equivalent concentration exceeds the aqueous solubility of TCE, reflecting the presence of TCE liquid. DCA: 5 mM (495 mg/L), Na₂S₂O₈: 6.3 mM (1,500 mg/L), H₂O₂: 150 mM (5,100 mg/L), siderite: 11,450 mg/L. These oxidant concentrations are relatively low compared to typical concentrations used for field applications. Thus, these concentrations will produce conservative results.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
