A methodology for the simultaneous detection of several heavy metals in water samples is described in detail. Targets were chemically prepared by preconcentration of the metals. Characteristics of the proton beam and X-ray detection are summarized. The concentration was obtained by using an internal standard in the range ppb-ppm.

Abstract

A methodology for the simultaneous detection of several heavy metals in water samples is described in detail. Targets were chemically prepared by preconcentration of the metals. Characteristics of the proton beam and X-ray detection are summarized. The concentration was obtained by using an internal standard in the range ppb-ppm. The method was tested by calibration with samples of known concentration. The subtraction of background and the data processing are discussed. The error in each concentration is evaluated.
