【24h】 Environmental Technology Verification Report: Field Portable X-ray Fluorescence211 Analyzer; Scitec MAP Spectrum Analyzer

【摘要】In April 1995, the U.S. Environmental Protection Agency (EPA) conducted a211u001edemonstration of field portable X-ray fluorescence (FPXRF) analyzers. The primary 211u001eobjectives of this demonstration were: (1) to determine how well FPXRF analyzers 211u001eperform in comparison to standard reference methods, (2) to identify the effects 211u001eof sample matrix variations on the performance of FPXRF, (3) to determine the 211u001elogistical and economic resources needed to operate FPXRF analyzers, and (4) to 211u001etest and validate an SW-846 draft method for FPXRF analysis. The demonstration 211u001edesign was subjected to extensive review and comment by the EPA's National 211u001eExposure Research Laboratory, EPA Regional and Headquarters Superfund technical 211u001estaff, the EPA's Office of Solid Waste-Methods Section, and the technology 211u001edevelopers. Two sites were used for this demonstration: the RV Hopkins site and 211u001ethe ASARCO Tacoma Smelter site (ASARCO). RV Hopkins is an active steel drum 211u001erecycling facility and a former battery recycling operation. It is located in 211u001eDavenport, Iowa. The ASARCO site is a former copper and lead smelter and is 211u001elocated in Tacoma, Washington. The test samples analyzed during this 211u001edemonstration were evenly distributed between three distinct soil textures: sand, 211u001eloam, and clay.
