The following elements are determined by atomic absorption techniques using a <br />• Perkin-Elmer 5000 Atomic Absorption Spectrophotometer equipped with autosampling <br />capability. All light sources are single element hollow cathode Tubes. <br />Calcium -Determined at a wavelength of 422.7 nm using an air- <br />acetylene flame. The detection limit is 0.06 mg/I. Calcium is reported in rng/liter. <br />Mognesium -Determined at a wavelength of 285.2 nrn using an air- <br />acetylene flame. The detection limit is 0.005 mg/I. Magnesium is reported in mg/liter. <br />Lead -Determined at a wavelength of 283.3 nrn using a flameless <br />graphite furnace to effect atomization. The detection limit is 0.005 mg/I. Lead is <br />reported in mg/liter. <br />Manganese -Determined ai a wavelength of 279.5 nm using an air- <br />acetylene flame. The detection limit is 0.04 mg/I. Manganese is reported in mg/liter. <br />Nickel -Determined at a wavelength of 232.0 nm using an air-acetylene <br />flame. The detection limit is 0.1 mg/I. Nickel is reported in mg/liter. <br />Zinc -Determined at a wavelength of 213.9 nrn using an air-acetylene <br />flame. Detection limit is 0.01 rng/I. Zinc is reported in mg/liter. <br />Copper -Determined at a wavelength of 324.8 nrn using an air-acetylene flame. <br />Detection limit is 0.06 rng/I. Copper is reported in rng/liter. <br />. Chromium (Flexavalent) -The sample is extracted with <br />methylisobvtyl ketone (MIBK), in which Cr (VI) is soluble. Chromium (VI) is then <br />determined on the MIBK extract at a wavelength of 357.9 nrn using a nitrous oxide- <br />acetylene flame. The detection limit is 0.05 mg/I. Chromium (VI) is reported in <br />mg/liter. <br />Mercury -The sample is treated with hydroxylamine hydrochloride <br />followed by stannous chloride to produce elemental mercury, which is swept out of <br />solution with argon. Mercury is then determined at a wavelength of 253.7 nrn without <br />o flame. The detection limit is 0.001 rng/I. Mercury is reported in mg/liter. <br />Sodium -Determined by flame emission photometry ai a wavelength <br />of 589.0 nm using an air-acetylene flame. The detection limit is 0.01 rng/I. Sodium is <br />reported in mg/liter. <br />Potassium -Determined by flame emission photometry at a wavelength <br />of 766.5 n-n using an air-acetylene flame. The detection limit is 0.005 rng/I. Potassium <br />is reported in mg/liter. <br />Iron -Determined at a wavelength of 248.3 nrn using an oir-acetylene <br />flame. The detection limit is 0.08 mg/I. Iron is reported in mg/liter. <br />• Aluminum -Determined by atomic absorption in a nitrous oxide- <br />2.5-112 <br />
