  • The influence of reaction conditions in the oxidation of organic compounds of nuclear laundry water by ozone

    This paper presents a summary of degrading organic compounds of nuclear laundry water by ozonation in different conditions of pH, hydrogen peroxide and ultraviolet radiation. The degradation of organic compounds was analysed by chemical oxygen demand (COD), total organic carbon (TOC) and biochemical oxygen demand (BOD). The optimal degradation conditions were at pH 7 with ozone, UV radiation and ...

  • Fast GC In Environmental Analysis

    Fast GC can be practical for many environmental analyses, and may not require a major investment in new equipment.  By applying the techniques of Fast GC such as, using shorter, narrower bore columns, faster oven temperature ramp rates, hydrogen carrier gas, and by taking advantage of the variety of column chemistries available in fast dimensions, analyses times can be significantly reduced ...

  • The photoreaction of TiO
    2
    and Au/TiO
    2
    single crystal and powder with organic adsorbates

    The review deals with the principles of photoreactions over TiO2 with emphasis on both single crystals and nano particles. The main fundamental reactions of prototype organic compounds are given and analysed. Hydrogen production from alcohols as an example of sustainable production of energy carriers is also presented and discussed. After an overview of the ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Removal and transformation products of ibuprofen obtained during ozone- and ultrasound-based oxidative treatment

    The oxidation of ibuprofen (IBP) in water was evaluated using oxidative treatments: ozonation, sonication, hydrogen peroxide addition and combinations of these processes. After 20 minutes of treatment, ozone coupled with hydrogen peroxide at pH 7, 15 °C, an ozone dose of 16 mg/L and a hydrogen peroxide concentration of 7.1 mg/L was found to have the highest IBP (95%) and chemical ...
