【Abstract】 The sample is pretreated with magnesium nitrate by means of dry-ashing method, the contents of lead and cadmium in leather was determinated by flame atomic absorption spectrometry. The RSD for lead and cadmium are 8.3%, 11.6%; their recoveries tested by standard addition method are 84.2%-93.5%,88.2%-91.3%?更多还原
