  • Ozone Artifacts and Carbonyl Measurements Using Tenax GR, Tenax TA, Carbopack B, and Carbopack X Adsorbents

    INTRODUCTION Sampling of airborne volatile organic compounds (VOCs) using thermally desorbable solid adsorbents has proven its usefulness in many environmental applications and has become a routine technique1 with compelling advantages over canisters, especially when a large sample volume or sample transport is needed.2 Many adsorbents are available, and users are faced with the difficulty of ...

  • Comparative study on metal ions adsorption on a low cost carbonaceous adsorbent kinetic equilibrium and mechanistic studies

    Wastewater generally contains toxic inorganic and organic pollutants. Inorganic pollutants consist of mineral acids, inorganic salts, finely divided metal compounds, trace elements, cyanides, nutrients and organometallic compounds. Some of the trace elements play essential roles in biological processes, but at higher concentrations, they may be toxic to the biota; they disturb the biochemical ...

  • Estimating the fates of organic contaminants in an aquifer using QSAR

    The quantitative structure activity relationship (QSAR) model, BIOWIN, was modified to more accurately estimate the fates of organic contaminants in an aquifer. The predictions from BIOWIN were modified to include oxidation and sorption effects. The predictive model therefore included the effects of sorption, biodegradation, and oxidation. A total of 35 organic compounds were used to validate ...
