| Abstract: | The amount of heavy metal in vetiveria grass is studied.Trace Pb,Cd and Cu in Vetiveria grass has been determined by graphite furnace atomic absorption spectrometry(GFAAS).After a series of experiments,the best ashing temperature and atomic temperature to determine Pb,Cd and Cu are decided.The method is simple,rapid,accuracy,requires little sample and has high recovery. |
