| Abstract: | In this study an E S method has heen pro-posed,in which KH_2PO_4 is used as the carrier,In and Pd as the internal standards,flat head graphite electrode as the working electrode .and 6A alternating current are as the lightsource. The solution residue technique and amodel WSP-1 Spectrometer were used.In asmall sample of about several ten milligrams,13 elements (Be,V,Cr,Ni,Fe,Cu,Sn,Ti,Pb,Mn,Zn,Cd and Co)were simultaneouslydetmrmined,The results Show that thismethod is fast and sensitive,and its precisionand aecuracy can meet the requirements of en-vironmentrql analysis.This mctbod has been used for The deter-mination of metallic elements contained theirdistribution in airborn particulates in Cheng-du. |
