| Abstract: | The present paper describes an metastable energy transfer emission spectrometry(MTES) for the determination of zinc. When N2 was used as support gas, the active nitrogen afterglow was produced in a microwave discharge. The sample solution was introduced with an electrothermal microsam-pie introduction system, the experimental parameters affecting the determination of zinc were examined, zinc was determined at 472. 2 nm and the detection limit was 2. 3 ng. The method has been employed to analyse the practical samples and the result is satisfactory. |
