摘要:
Atomic emission spectroscopy (AES) is an essential topic within theundergraduate analytical chemistry curriculum. A 1991 study found that 43% of the schools teachingan instrumental analysis course featured an AES experiment, making it one of the most prevalentexperimental techniques is this course (1). A number of AES laboratory experiments have alsoappeared in the chemical education literature over the years (2-4), with common themes beingquantitative flame emission procedures for a particular elements (5-7) or construction of aninexpensive spectrometer to measure emission signals in the undergraduate laboratory (1,8,9). Thedevelopment and implementation of the inductively coupled plasma (ICP) source for AES has yieldedmany advantages over flame emission, most of which derive from the greater temperature of the plasma(10). Widespread industrial use snd a drop in unit price now encourage consideration of ICPexperiments for inclusion in the undergraduate curriculum.
