Multi-element Analysis of Sediments by ICP-OES with Radial and Axial Plasma Observation
The analysis of sediment is of interest to geologist and relevant government bodies because of their impact on the heavy metal contamination on the aquatic environment. The accumulation of heavy metals in sediments causes a potential risk to human health due to the transfer of those elements to aquatic media, uptake by plants and their subsequent introduction into the food chain . Various countries use Sediment Quality Guidelines (SQG) to monitor total metal contents and maximum concentration levels of trace elements . Additionally, the analysis of rock is of interest to mining companies because of economically viable elements present in them.
Inductively coupled plasma optical emission spectrometry (ICP-OES) is a method of choice for the analysis of rock and sediments, due to its multi-element determination capability, high dynamic linear range, sensitivity and robustness.
