Abstract

The organochromium content of sewage sludge was evaluated during this study. Sewage sludges containing chromium were obtained. These sludges were analyzed to determine total chromium and then fractionated to obtain four chromium fractions. The fractions represented soluble chromium, cationic chromium which was dilute acid soluble, and alkali soluble and insoluble fractions. The two later fractions represent the chromium which is associated with humus and humin respectively. Mixtures of the sludges were analyzed for total and fractionated chromium. These mixtures were then subjected to aerobic and anaerobic digestion for 30 days. After the 30 day period the sludge mixtures were reanalyzed. Good mass balances were obtained for both the distribution of chromium among fractions compared with total chromium analyses and between before and after digestion samples. Data also was collected from the four fractions described earlier (for twenty-two other elements). These data were collected for sludge mixtures both before and after digestion studies. Comparisons were made of the distribution of the various elements.
