| Abstract: | Cu in polygonatum odoratum(MiLL) druce is determined by FAAS adopting suspension sample intruction.Samples are dried,sieved and made into agar suspension to be injected into air-acetylene flame for determination.Recovery rate of standard addition is 97.8%～99.7%.RSD is less than 2.5% and the detection limit is 0.0038(g/mL. |
