| Abstract: | The sample was digested by ashing method,Cr,Ag,Zn,Ni,Cd,Fe and Cu in P.vulgaris stem were determined using flame atomic absorption spectrometry.The results showed that the contents of trace elements Cr,Zn,Ni,Cd,Fe and Cu in P.vulgaris f stem as follow 4.040,11.824,3.896,0.080,71.920,12.440 μg/g,except Ag was undetected.The sequence of tested trace element contents was Fe>Cu>Zn >Cr>Ni>Cd.The recovery rate by atomic absorption was 98.6% to 111.1% and the analysis method is simple,rapid.It was f... |
