title: The effect of incomplete spike reaction on the determination of trace metals in a complexing matrix by standard additions.
abstract: In the determination of trace metals, a preconcentration step is frequently necessary. A simple model is developed to demonstrate the magnitude of the error incurred in the application of the standard-additions method if full equilibration of the spike with a sample matrix that contains complexing species is not reached before the preconcentration is completed.
