COMPARATIVE EVALUATION OF METHODS OF SELENIUM ANALYSIS FOR DETERMINING POTENTIAL

Abstract:

A study was undertaken to evaluate extraction procedures designed to predict the

leachability of selenium in sediments and overburden from reclaimed mine lands.

The four extraction procedures evaluated in this study were the 1) Synthetic

Groundwater Leaching Procedure (SGLP), 2) Synthetic Acid Rain Leaching

Procedure, 3) Hot-Water-Soluble Extraction and 4) Ammonium

Bicarbonate-Diethylenetriaminepentaacetic Acid. The results indicated good

correlation among the procedures with respect to selenium mobility. Analytical

methods (furnace atomic absorption spectroscopy, inductively coupled argon

plasma spectroscopy, and hydride generation) were also evaluated to determine

the most appropriate analytical techniques. The SGLP provided the data most

likely to parallel natural field phenomena while providing solutions for

analysis unlikely to contain elements that would interfere with selenium

determination.

Leaching of overburden cores suggested that total and leachable selenium might

be related to lithology. Scanning electron microscopy/microprobe studies

suggested disseminated sources in organic matter. Sand and silt beds were

selenium deficient and carbonaceous beds enriched, focusing attention on

selected zones in geologic section.

Selenium content was mapped using existing geologic sections to project

concentrations along and within key lithogic and stratigraphic units across the

mine. This required spatial reconstruction of stratigraphy based on

depositional environments, providing a superior method for extrapolating

selenium into data poor areas optimizing sampling/analysis resources.
