摘要: A technique combining ultrasonic nebulization of solutions and graphite-furnace atomic-absorption spectrometry is described. The analytical possibilities two different techniques are shown. In one the nebulized samples continuously introduced into a graphite tube operated at constant temperature, in other deposited on inner wall heated discontinuously. method chosen influences absorption values for several elements. sensitivity determination by continuous sampling lies between normal electrothermal AAS injection flame AAS. Higher sensitivities obtained with deposition technique.
