Abstract
The decontamination of pentachlorophenol (PCP) laden soil was investigated. PCP was extracted from the soil followed by degradation by Flavobacterium sp. Extractions were performed on whole soil with aqueous solutions, and the amount of PCP increased with NaOH concentration. The efficiency of extraction was found to be relatively low. The distribution of PCP in the particles was uneven. The smaller, slower settling particles contained most of the contaminant, while the larger particles, which constituted most of the soil mass were found to be contaminated to a lesser extent. We thus devised a scheme of separate treatment of the two fractions of the soil. The coarse, or sand, fraction was decontaminated by alkaline extraction. The PCP present in the extracts was then degraded by cells of Flavobacterium sp. The fraction of the smaller particles (i.e., fines) was treated by direct inoculation with cells of Flavobacterium sp.
