Abstract
Flame atomic absorption spectrometry(FAAS) was used to detect Cu content in soil.SiO2 which is in the solid was droved off by HNO3-HF and then the sample was dissolved in it.The detection limit of this method was 0.016mg·L-1 and,the accurate was 0.62%—1.01%,recovery is 98.0%—99.2%.Acceptable result was achieved for detecting national quality control samples by this method.
