Abstract
![CDATA[Granular activated carbon (GAC) has been extensively used to remove trace metals from drinking water. We have used PIXE to quantify trace metals, in particular, arsenic in GAC. The results were compared with atomic absorption spectrophotometry (AAS). Some differences have been observed between these two measurements mainly due to the inhomogeneous structure of GAC. 1. Introduction: Granular activated carbon (GAC) has been extensively used to remove trace metals from drinking water for a number of years because it is a highly cost effective treatment on a small scale. To date, there has been no published literature on non-destructive methods to quantify the actual amount of trace metals adsorbed by the GAC directly. Proton induced X-ray emission (PIXE) is an ideal analytical tool, which is suitable for simultaneously quantifying trace elements with sensitivity of at least parts per million (ppm).]]
