Abstract
Wastewater streams must be closely monitored, enabling an immediate reaction to any change, in this way avoiding environmental damage and unnecessary expenses. A task that became increasingly important with the obligation to comply with stringent environmental regulations.
On-line energy dispersive X-ray Fluorescence (EDXRF) technology, which is robust and non-destructive with low detection limits and highly accurate and reproducible analysis results offers the possibility to monitor elements from sodium up to americium at concentrations from a few ppm to 100%. On-line EDXRF technology can be tailored to industrial needs with optional sample conditioning and can be incorporated in many different process streams in a wide range of industries, including mining and metals independent of the location within the process flow of wastewater or upstream processing.
The practical use of EDXRF on-line elemental analysis for the direct monitoring of wastewater and process streams in the mining and minerals industry will be illustrated.
