Abstract
Solvent extraction of pentachlorophenol (PCP) from wood chips of the PCP-treated ammunition box has been studied using methanol, ethanol and acetonitrile. Experimental variables were chosen as the composition of solvents, the ratio of solvent per dried wood, size of the substance, extraction temperature and sonication applied to the samples. The average concentration of PCP was 720 ppm and methanol was the most effective for PCP extraction. Above 99％ of PCP were removed from the sample (initial concentration of PCP; 1297 ppm) within 2 h at room temperature by methanol. The minimal ratio of methanol per dried wood chip(v/w) was 10. Type of substances(chip or sawdust), extraction temperature and sonication showed little effects on PCP extraction.
