| Abstract: | Microwave plasma torch for the determination of trace cadmium is described. Some excitation performance of MPT has been studied and discussed. The sample solution was introduced with an electrothermal microsample introduction system. The experimental parameters affecting the determination of cadmium were examined in details. Cadmium determined at 228.8 nm and the detection limit was 0.28ng/ml. The method has been employed to analyse the real samples and the result is satisfactory. |
