Abstract

Abstract: In this paper, the probability of eliminating matrix interferences in MPT-AES by on-line standard addition method was studied. The dynamic linear range of Cu and Mg is 0. 05～80 μg/mL.The relative standard deviations of them are 3.02% (1.0 μg/mL, n=7).and 4.47 % (1. 0 μg/mL, n=7) respectively. The results indicated that this method can eliminate matrix interferences and is useful in real sample analysis. The operation of this system is simple.

Key words: On-line standard addition method, Microwave plasma torch, Atomic emission spectrometry
