Innovative Technology Verification Report: Field Measurement Technology for Mercury in Soil and Sediment. MTI Inc.'s PDV 6000 Anodic Stripping Voltammetry;Symposium paper

摘要

Monitoring Technologies International Pty. Ltd. (MTI) has developed a Portable Digital Voltammeter (PDV) designed to identify and measure the concentration of heavy metal ions. MTI's PDV 6000 was demonstrated under the U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation Program in June 2003 in Las Vegas, Nevada. The purpose of the Demonstration was to collect reliable performance and cost data for the PDV 6000. Four other field measurement devices for mercury in soil and sediment were evaluated in May 2003 at the Oak Ridge National Laboratory in Oak Ridge, Tennessee. The key objectives of the Demonstration were: (1) determine sensitivity of each instrument with respect to a vendor-generated method detection limit (MDL) and practical quantitation limit (POL)$ (2) determine potential analytical accuracy associated with vendor field measurements$ (3) evaluate the precision of vendor field measurements$ (4) measure time required to perform mercury measurements$ and (5) estimate costs associated with mercury measurements for capital, labor, supplies, and investigation-derived wastes (IDW).
