  • Vapor sorption isotherms of ethylene glycol monoethyl ether (EGME) at room temperature and isotherms of N[sub 2] gas at liquid nitrogen temperature were determined for various soils and minerals. The N[sub 2] monolayer capacities [Q[sub m](N[sub 2])] were calculated from the BET equation and used to determine the surface areas. To examine whether EGME is an appropriate adsorbate for determination of surface areas, the apparent EGME monolayer capacities [Q[sub m](EGME)[sub ap]] were also obtained by use of the BET equation. For sand, aluminum oxide, kaolinite, hematite, and synthetic hydrous iron oxide, which are relatively free of organic impurity and expanding/solvatingmore » minerals, the Q[sub m] (EGME)[sub ap] values are in good conformity with the corresponding Q[sub m] (N[sub 2]) values and would give surface areas consistent with BET (N[sub 2]) values. For other samples (Woodburn soil, a natural hydrous iron oxide, illite, and montmorillonite), the Q[sub m] (EGME)[sub ap] values overestimate the Q[sub m] (N[sub 2]) values from a moderate to a large extent, depending on the sample. A high-organic-content peat shows a very small BET (N[sub 2]) surface area; the EGME/peat isotherm is linear and does not yield a calculation of the surface area. Large discrepancies between results of the two methods for some samples are attributed to the high solubility of polar EGME in soil organic matter and/or to the cation solvation of EGME with solvating clays. The agreement for other samples is illustrative of the consistency of the BET method when different adsorbates are used, so long as they do not exhibit bulk penetration and/or cation solvation. 26 refs., 7 figs., 2 tabs.« less
  • Subcritical water extraction was used as a tool to remove the carboxylic, aliphatic, and carbohydrate types of organic carbon from a humic soil. The rates and extents of soil organic carbon removal were quantified as functions of superheated water temperature, phase, and exposure time. The experimental data suggest that superheated water effects deoxygenation/aromatization reactions of soil organic matter that mimic those of geologically slow, natural diagenesis processes. Phenanthrene sorption and desorption equilibrium isotherms for the altered soils were measured. The sorption isotherms were characterized by increasing capacity and nonlinearity with increasing degree of polar functionality removal and simulated diagenesis ofmore » the soil organic matter.« less
  • A series of solid- and slurry-phase soil bioremediation experiments involving different crude oils and refined petroleum products were performed in order to investigate the factors which affect the maximum extent of total petroleum hydrocarbon (TPH) biodegradation. Utilizing a comprehensive petroleum hydrocarbon characterization procedure involving group type separation analyses, boiling point distributions, and hydrocarbon typing by field desorption mass spectroscopy, initial and final concentrations of specified hydrocarbon classes were determined in each of the seven bioremediation treatments. In this study, it was found that the degree of TPH biodegradation was mainly affected by the type of hydrocarbons in the contaminant matrixmore » while the influence of experimental variables such as soil type, fertilizer concentrations, microbial counts, and treatment type (slurry vs land-treatment) on the overall extent of TPH biodegradation appeared to be insignificant. Based on these findings, a predictive algorithm was developed to estimate the extent of TPH biodegradation from the average reduction of 86 individual hydrocarbon classes and their respective initial concentrations. Model predictions for gravimetric TPH removals were in close agreement with analytical results from two independent laboratories. 40 refs., 8 figs., 3 tabs.« less
  • Contaminant sorption by soils and sediments is characterized as a multiple reaction phenomenon. The approach is predicated on the observation that most natural soils and sediments are intrinsically heterogeneous even at the microscopic scale; that is, variable in composition and structure at both interparticle and intraparticle scales. Heterogeneity is demonstrated for a number of soils which, on the basis of conventional macroscopic properties, would be considered homogeneous. That such heterogeneities are reflected in sorption reactions which differ between soils and between different fractions of soil is also demonstrated. A composite model, the distributed reactivity model (DRM), is introduced to characterizemore » intrinsic heterogeneities in the properties and behaviors of soils and sediments and to capture the resulting nonlinearities of sorption isotherms. Finally, the significance of particle-scale heterogeneity and distributed reactivity is illustrated by using measured parameters and DRM calculations to characterize differences in the relative sorption behavior of soils comprising different mass fractions of differently reactive components. 31 refs., 9 figs., 2 tabs.« less
  • The uptake of individual hydrophobic organic compounds (HOCs) from aqueous solution by soils which exhibit heterogeneous reactivity is shown to be reduced in the presence of other HOCs. The observed behavior is consistent with expectations for competitive surface adsorption phenomena, being most marked at low solution-phase concentrations and coinciding with single-solute isothermal nonlinearity. Nonlinear sorption and competitive effects appear to relate to components or fractions of soil having different reactivity than that commonly attributed to soil organic matter. In particular, HOC uptake by the organic components of soils deriving from certain sedimentary rocks appears to occur by surface reactions rathermore » than by partitioning to organic matrices. Ideal adsorbed solution theory (IAST) is used to predict mixed-solute competitive effects from single-solute sorption isotherms. The results are examined within the context of the distributed reactivity model (DRM), wherein overall sorption behavior by heterogeneous solids is explicitly attributed to different mechanisms. Competitive reductions in the sorption of HOCs in systems dominated by nonlinearly sorbing soil components and characterized by a two-compartment DRM are found to be modeled reasonably well with IAST. 22 refs., 12 figs., 3 tabs.« less
