| Abstract: | In this paper, Cd was determined by microwave plasma torch atomic emission spectrometry (MPT AES) using on line separation and concentration with a strongly acidic anion exchange resin(type 717) as the column packed material. The effect of microwave radiation on the separation and concentration was investigated. The experimental results indicated that under microwave field, the speed up of preconcentration and elution and the increase of emission intensity of analyte were observed. |
