| Abstract | Trace metals in water collected in small pore filter paper and ion exchange filter paper were analyzed by the X-ray fluorescence method. The procedures necessary for the X-ray fluorescence method are described as well as modifications possible for special problem situations. A number of outfalls on the Great Miami River were sampled over one year showing the presence of the following metals, Ca, Ti, Cr, Fe, Cu, Zn, Sr, Cd, and Cr. Elements in the periodic table between Ti and Cs were seen to a sensitivity limit of the order of 30 ppb. A computer program for analyzing the X-ray fluorescent spectra qualitatively and quantitatively is described, including a calibration scheme. The effects of absorption and enhancement are analyzed. A review is included of the toxilogical effects of trace metals. (Author) |
