Title: Rapid Column Extraction method for SoilRapid Column Extraction method for Soil

Abstract

The analysis of actinides in environmental soil and sediment samples is very important for environmental monitoring as well as for emergency preparedness. A new, rapid actinide separation method has been developed and implemented that provides total dissolution of large soil samples, high chemical recoveries and effective removal of matrix interferences. This method uses stacked TEVA Resin{reg_sign}, TRU Resin{reg_sign} and DGA-Resin{reg_sign} cartridges from Eichrom Technologies (Darien, IL, USA) that allows the rapid separation of plutonium (Pu) neptunium (Np), uranium (U), americium (Am), and curium (Cm) using a single multi-stage column combined with alpha spectrometry. The method combines a rapid fusion step for total dissolution to dissolve refractory analytes and matrix removal using cerium fluoride precipitation to remove the difficult soil matrix. By using vacuum box cartridge technology with rapid flow rates, sample preparation time is minimized.

  • This article presents rapid methods for the extraction and subsequent analysis of organics in soils potentially contaminated from chemical wastes. A methylene chloride extraction, on both a micro scale in a syringe and a macro scale in a shaken flask, with subsequent gravimetric analysis are described. On wet soils, anhydrous sodium sulfate is added to bind the water before adding methylene chloride and mixing with a vortex touch mixer. A baseline procedure is the direct gravimetric determination of volatile organics corrected with a Karl Fischer determination of water. Estimates of time saved by using the rapid methods, as well asmore » precision and accuracy data, are presented.« less
  • Volatile organic compounds (VOCs) are among the most common chemical pollutants tested for in soil, sludge, drinking water and waste water. The US EPA methods describe the use of thick-film capillary columns for separating VOCs. Methods 502.2, 524.2, 624.2, 8,240, 8,260 and CLP-VOA normally specify purge-and-trap sample preparation/introduction systems connected to 0.530 mm ID fused silica columns. These requirements have been satisfied with long 0.53 mm ID capillary GC columns (75--105m), thick stationary phase films (3.0 {micro}m) and unique stationary phases. However, each purge-and-trap analysis takes 60--90 minutes to complete. The authors demonstrate VOC analyses performed with short, small-diameter openmore » tubular columns via purge-and-trap with continuous splitting and via solid phase microextraction (SPME). The goal for this work was to reduce total analysis time by reducing the GC cycle time and sample extraction time. Comparison of purge-and-trap and SPME of VOCs in soil will be examined in order to accomplish the goal.« less
  • This Phase I Small Business Innovation Research program is confirming the effectiveness of a bio-reagent to cost-effectively and selectively extract a wide range of heavy metals and radionuclide contaminants from soil. This bioreagent solution, developed by ISOTRON{reg_sign} Corporation (New Orleans, LA), is flushed through the soil and recycled after flowing through an electrokinetic separation module, also developed by ISOTRON{reg_sign}. The process is ex situ, and the soil remains in its transport container through the decontamination process. The transport container can be a fiberglass box, or a bulk bag or {open_quotes}super sack.{close_quotes} Rocks, vegetation, roots, etc. need not be removed. Highmore » clay content soils are accommodated. The process provides rapid injection of reagent solution, and when needed, sand is introduced to speed up the heap leach step. The concentrated waste form is eventually solidified. The bio-reagent is essentially a natural product, therefore any solubizer residual in soil is not expected to cause regulatory concern. The Phase I work will confirm the effectiveness of this bio-reagent on a wide range of contaminants, and the engineering parameters that are needed to carry out a full-scale demonstration of the process. ISOTRON{reg_sign} scientists will work with contaminated soil from Los Alamos National Laboratory. LANL is in the process of decontaminating and decommissioning more than 300 sites within its complex, many of which contain heavy metals or radionuclides; some are mixed wastes containing TCE, PCB, and metals.« less
  • The SRS Environmental Laboratory analyzes water samples for environmental monitoring, including river water and ground water samples. A new, faster actinide and strontium 89/90 separation method has been developed and implemented to improve productivity, reduce labor costs and add capacity to this laboratory. This method uses stacked TEVA Resin{reg_sign}, TRU Resin{reg_sign} and Sr-Resin{reg_sign} cartridges from Eichrom Technologies (Darien, IL, USA) that allows the rapid separation of plutonium (Pu), neptunium (Np), uranium (U), americium (Am), curium (Cm) and thorium (Th) using a single multi-stage column combined with alpha spectrometry. By using vacuum box cartridge technology with rapid flow rates, sample preparationmore » time is minimized. The method can be used for routine analysis or as a rapid method for emergency preparedness. Thorium and curium are often analyzed separately due to the interference of the daughter of Th-229 tracer, actinium (Ac)-225, on curium isotopes when measured by alpha spectrometry. This new method also adds a separation step using DGA Resin{reg_sign}, (Diglycolamide Resin, Eichrom Technologies) to remove Ac-225 and allow the separation and analysis of thorium isotopes and curium isotopes at the same time.« less
