“…It is the most realistic and economical way to treat it for the supplement of drinking water because of its relatively clean quality [2]. Sorption-catalytic oxidation of HC was employed with high efficiency, where Pt was used as the catalyst and oxygen as the oxidizer [3,4]. However, the method suffered from high consumption of adsorbents and energy, and the operating cost was high.…”

A condensing heat exchanger has been used to collect humidity condensates during two space shuttle missions. Analyses of the reclaimed waters indicate the presence of short chain ' alcohols, carboxylic acids and other hydrophilic low molecular weight organics which originate as airborne contaminants consequent to human metabolism and materials outgassing. To better understand aqueous phase oxidation processes proposed for the mineralization of these dissolved organics, the thermodynamics of combustion of the predominant species to CO 2 (aq) and H 2 O( ) have been examined. The relationships between temperature, ΔH, ΔS, and ΔG for the mineralization reactions have been derived for nine of the most significant contaminants and fitted to a fourth degree polynomial with excellent results. These data were then used to calculate values of the three aforementioned thermodynamic properties as functions of reaction temperature for the complete oxidation of the two humidity condensates. The results indicate that the enthalpy of combustion will result in only minor heating of the aqueous phase.
