Özet
Introduction of sample solutions into the flame atomic absorption spectroscopy (AAS) via electrically heated metal loops notably improves the detection limits of the technique. However, because of the low melting point of platinum (1772 degrees C) application of the loop technique is limited only to sufficiently volatile elements. In this work interference encountered with a Pt-loop atomizer is reviewed and chemical interference is found to be the most important factor limiting its applications. Therefore, a separation/enrichment step in the analytical scheme is needed not only for the enrichment of the analyte itself but also to ensure that the chemical form of the analyte in both standard and sample solutions is the same. Samples of soil extracts, fertilizers, waste water of domestic origin and air samples have been chosen to demonstrate the environmental application of the loop technique.
