“…This observation may provide a third important reason for using phosphoric acid. The literature on the effect of phosphate in the atomic absorbance analysis of aluminum at higher concentration (e.g., 0.1 ppm) (13,18) is contradictory, with our results tending to support Garmestani et ah (18). They found, as did we, that phosphate enhances considerably the aluminum signal, even at these much higher concentrations.…”

“…Received for review July 18,1985 The aluminum concentration of precipitation is a necessary measurement for the determination of noncrustal contributions to the precipitations' trace element content (1,2). The measurement of aluminum concentration is part of an ongoing study of the trace elements in remote U.S. west coast precipitation.…”

“…When the series of CaCl2 solutions was atomized from the wall of a standard furnace, there was no large suppression of the analytical signal, although the data did not follow a very regular trend, as shown in Figure 2. For contrast, we have plotted points from the work of Matsusaki et al (30) and Garmestami et al (31), who have studied the same system. We have not seen the great suppression of signal they reported.…”

Recent Improvements in the graphite furnace have greatly reduced analytical interferences. Problems remain that appear to be related to the poroslty of graphite and to the fraglllty of pyrolytlc graphlte protectlve coatings. We compare graphite tubes from several sources which have been coated in several different ways for their differences In analytlcal sensitlvlty for Cu, AI, Sr, TI, and Mo. A separate set of experiments using the determlnatlon of AI In a chloride matrlx shows even greater variation between graphlte materials prepared differently. Experiments uslng the graphlte furnace at steady-state temperature, in the platform and probe variatlons, showed less than 10% signal suppression from 50 pg of CaCI, or CuCI, on 2 ng of AI.Our recent papers (1-6) have attempted to improve the analytical conditions for trace metal determination with the graphite furnace and atomic absorption spectroscopy. When the furnace is operated at a steady-state temperature (2, 3, 5-9) during the time the analyte is vaporized and the absorbance signal is integrated

The problems regarding storage and pre-neutron activation analysis treatment for the elements aluminrun. calcium, vanadium, selenium, copper, iodine, zinc, manganese, and magnesium in a urine matrix are reviewed. The type of collection and storage procedure and pre-neutron activation analysis treatment of urine depend on the specific trace element; that is, its inherent physical and chemical properties. Specifically polyethylene in teflon containers are the most suitable for general determinations. Whether any preservative is added would depend upon the stability of the trace element and its tendency for surface adsorption. Preferably preservatives should contain no radioactivatable elements for maximum efficacy. Freeze drying or packing urine shipments under dry ice needs to be explored on an individual basis. Each pre-or post-neutron activation analysis treatment is specific and optimized for the trace element analyzed.
