Performance Comparison Between Two Different Absorption Cells Used in MIP-AAS for Determination of Nickel

Abstract

Abstract: A systematic performance comparison between two different absorption cells used in MIP-AAS for the determination of nickel is completed in this paper.Various factors,such as microwave forward power,carrier gas flow rate,the acidity of the sample solution,etc.,which affected the absorbance,were studied and compared with each other in detail.The effects caused by easily ionized elements and some concomitant elements were also examined for this purpose.A significant enhancement in sensitivity was observed in the determination of nickel when Ca,Mg or La existed.Some conclusions about the performance of T-shaped and L-shaped absorption cells were made

Key words: Microwave induced plasma, Atomic absorption spectrometry, Discharge-absorption cells, Determination of nickel
