Seven samples of deep-sea ferromanganese nodules from the Pacific and Atlantic Oceans were analyzed by proton-induced X-ray emission (PIXE). The concentrations of Na, Mg, Al, Si, K, Ca, Ti, V, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Mo, Ba, Tl and Pb in the nodules were determined, and the accuracy of the determinations was verified independently by flame atomic absorption and emission techniques. Thin sample targets on Nuclepore filter disks backed with Kapton were used with 1-MeV protons for the low-energy region (0 to 8 keV) and 2-MeV protons and a 0.004-in. al filter for the high-energy region (5 to 35 keV) of the X-ray spectrum. X-ray yield data were obtained for elements from Na to U (11 < Z < 92), with standards of 99.999% purity and the thin target technqiue. Five different NBS standard reference materials (orchard leaves, pine needles, bovine liver, coal, and coal fly ash) were analyzed by this method to determine the precision and accuracy that could be achieved under the operating conditions of the PIXE system. 4 figures, 6 tables.
