摘要：

The Spectraspan dc plasma emission spectrometer is evaluated an an analysis tool for the determination of trace heavy metals (cadmium, chromium, copper, lead, nickel, and zinc) in seawater and acid digestates of ocean sediments. Sodium, calcium, and magnesium in seawater are shown to increase both the background and elemental line emission intensities. Optimum analytical emission lines and detection limits are reported. Analytical precision is evaluated by replicate standard addition analyses of known solutions. © 1979, American Chemical Society. All rights reserved.
