长春市大气中PM2.5的重金属形态分析

Journal of Jilin University Science Edition

Cu,Zn,Cd and Pb in PM_2.5  of Changchun were determined with Tesser extraction method. The content sequence of the four elements is Zn>Pb>Cd>Cu. Elements’ distribution characteristics in acid solution, iron and manganese oxides, organic state and residue state were analysed. More specifically Cu and Zn were mainly distributed in acid solution; the majority of Cd was in acid solution and iron and manganese oxides; but Pb was in acid solution, iron and manganese oxides and residue in general.

Abstract

ZHANG Meixiu, LIU Wanyi, ZHANG Zhenbin, HU Ying, LIU Miao. Cu,Zn,Cd and Pb in PM_2.5  of Changchun were determined with Tesser extraction method. The content sequence of the four elements is Zn>Pb>Cd>Cu. Elements’ distribution characteristics in acid solution, iron and manganese oxides, organic state and residue state were analysed. More specifically Cu and Zn were mainly distributed in acid solution; the majority of Cd was in acid solution and iron and manganese oxides; but Pb was in acid solution, iron and manganese oxides and residue in general.[J].Journal of Jilin University Science Edition, 2013, 51(04): 735-738.
