modified green rust, hydrophobic


Hydrophobic green rusts (GR) were produced using aerial oxidation of solutions containing bis (2-ethylhexyl) sulfosuccinate (BIS) and sodium N-lauroylsarcosinate (SNLS), iron (II) sulfate and sodium hydroxide. The synthesis was conduced at constant pH 8.0±0.1 for the duration of 1-3 hrs. Partition tests showed GRBIS and GRSNLS suspended in the organic phase (tetrachloroethylene). Through X-ray diffraction analysis both GRs exhibit similar patterns to Green Rust II, an inorganic form of GR. The kinetics of GR reductive dechlorination of carbon tetrachloride (CT) was investigated. CT at high concentrations was degraded at high percentages for GRBIS-3, 88.5% and GRSNLS-5, 97.6%. Their reactions were found to follow pseudo first-order kinetics with respect to CT with rate constants of 1.7 x 10-1 h-1 and 3.3 x 10-1 h-1, respectively. These rate constants were comparable to those measured for CT dechlorination by inorganic GRSO4 (hydrophilic GR) and organic GRC12 (hydrophobic GR). Of the maximum amount of chloride that could possibly be present only 34-64% from GRSNLS-4 and 7.4-38% from GRSNLS-5 was accounted for.
