Abstract
An automated system for the quantitative determination of dissolved metals such as Fe, Cu, Zn, Ca, Co, Ni, Cr, Hg, Se, and Pb in water is described. The system collects a water sample, preconcentrates the dissolved metals with ion-exchange paper automatically in a sample collection and preparation module (SCPM) controlled by a microprocessor computer, and then quantitates the metals with an energy-dispersive x-ray spectrophotometer. It has been demonstrated in the laboratory that the system can automatically and simultaneously quantitate dissolved multi-element metal ions in water in the concentration range of parts per million to parts per billion.
