摘要：

Results for the calibration of the direct sample insertion technique (DSI) with sediment standards are reported for inductively coupled plasma atomic emission spectrometry (ICP-AES). It has been found that internal standardization can compensate for variations in volatilization interferences and changes in excitation conditions between sediment standards, for elements of high and intermediate volatility (Cd, Cu, Hg, Mn, Pb and Zn). It has also been found that the method of standard additions allows accurate calibration of the technique. Sub-ppm detection limits were typical for elements of high and intermediate volatility.
