Definitions

  • This technology relates generally to water purification.
  • this invention relates to separation of dissolved or emulsified organic impurities from water.
  • the cellulosic body of the device is configured for absorption of the hydrophobic organic component from contaminated water.
  • the cellulosic body of the device is configured for filtration of the hydrophobic organic component from contaminated water.
  • the cellulosic body of the device is made of paper or cotton.
  • Figure 9 Typical thermogravimetric data for untreated water aliquots from emulsified oil-water mixture (1 :2, vol/vol) containing 1000 ppm SDS.
  • FIG. 13 is a schematic illustration of a system employing absorbent pillows for the removal of emulsified or dissolved organic impurities from water and describes a container for waste water treatment in which the mode of oil/hydrocarbon removal is absorption.
  • the waste water may contain free, emulsified or dissolved oil/hydrocarbon.
  • the container itself can be envisioned to have: (1) an opening through which the water to be treated is brought, (2) a vent to allow free flow of air, (3) a handle to access the interior of the container, and (4) a tap to remove purified water.
  • hydrocarbon/water (1 :2, vol/vol) mixture with the hydrocarbon portion consisting of benzene and toluene (1 :1 :2, vol/vol/vol). Hydrocarbon portion of the mixtures were selectively absorbed using octyl functionalized GB005 paper. Aliquots of each treated water were then analyzed using GC-MS and compared with the GC-MS data obtained for the corresponding water from untreated mixtures (See Table SI for GC-MS results for toluene).

Abstract

Des matériaux cellulosiques permettent l'absorption sélective d'hydrocarbures émulsionnés et dissous de l'eau. Des surfaces cellulosiques hydrophobes sont préparées au cours d'un procédé de silanisation en phase gazeuse. Le procédé d'utilisation de papier, de tissu de coton et de laine enduit(e) de 3,3,3-trifluoropropyle dans la séparation des hydrocarbures de l'eau est décrit en détail dans la présente description. Un oreiller fonctionnel est obtenu par encapsulation de coton hydrophile non traité dans un contenant en tissu de coton fonctionnalisé avec du 3,3,3-trifluoropropyle. L'oreiller repousse l'eau avec 100 % d'efficacité, et peut absorber de grands volumes d'hydrocarbures selon leur taille. La pureté de l'eau traitée est > 99 % pour des huiles émulsionnées. De plus, un papier hydrophobe peut extraire du benzène dissous de l'eau contaminée.
