Spectrochemical method for the determination of 36 elements in industrial effluent

LeRoy, V.M. / Lincoln, A.J.

A quantitative spectrochemical method is described for the determination of 36 elements in industrial effluent with limits of element sensitivities for the analytical curves in the 0.0005-0.1 mg/100 ml range. One set of analytical curves is used for all samples. The samples are weighed salt residues obtained through evaporation to dryness at 120 Cel. Any sample volume can be used. Matrix effects are significantly reduced by combining total energy burns in an argon-oxygen atmosphere with 1:6 salt to high purity graphite powder dilutions. Germanium dioxide, added to the graphite powder, is the internal standard. Conditions of analysis, salt weight ratios, preparation of standards, precision, and accuracy are discussed.
