ISGS 1983Figure 14. HPLC chromatogram of the LC-4 fraction from the benzene extract of fly ash W1. See Figure 2for identification of the numbered peaks.The infrared spectra of the LC-5 fractions were similar to the spectra ofthe LC-4 samples, except that the LC-5 fraction from I8 had anomalous andunassigned peaks at 2340 and 1690 cm-1 (Fig. 15). The W1 sample hadmore carbonyl peaks than the other fly ash samples (such as the peak at1630 cm-1) indicating the possible presence of additional a1 dehydes andketones. The 1675 cm-1 peak may be due to hydroxyl overtones.The HPLC chromatogram of the LC-5 fraction from the W1 fly ash extract(Fig. 16) showed numerous peaks with retention times in the same range asthose of PAHs. According to the Level 1 scheme, this fraction containsaromatics with pol ar functional groups.The infrared spectra of the LC-6 fractions for 15, 18, and W2 were quitesimilar, with strong hydroxyl, carboxyl, and carbonyl absorptions.

These latter peaks were probablyamino-nitrogen peaks. HPLC analysis showed that the sample probablycontained a-large number of phenolic compounds as we1 1 as other polararomatics (Fig. 18).Wave number (ern-' ISGS 1983Figure 17.
