| Abstract |
The objective of this work assignment was to conduct a single-laboratory evaluation of the Soxhlet Extraction Procedure (Method 3540, SW-846) for the analysis of hazardous waste components in spent diatomaceous earth filter materials. The validation consisted of two phases: Phase 1, in which accuracy and precision were evaluated with diatomaceous earth fortified with a variety of analytes; and Phase 2, in which precision was determined by analysis of diatomaceous earth fortified with pesticide manufacturing waste. Several fortification/homogenization procedures were proposed and evaluated to accomplish Phase 1 objectives. The results show Method 3540 to be both accurate (average recovery: 90%) and precise (average percent relative standard deviation: 8%) on the recovery of nonvolatile analytes from diatomaceous earth. |
