We established a rapid analytical method for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and Polychlorobenzenes (PCBzs) in samples of fly ash, bottom ash and sludge from municipal domestic and industrial waste incinerators. It was essentially consisted of hydrochloric acid treatment, benzene refluxing extraction and micro-silicagel and alumina column chromatography. The hydrochloric acid treatment was effective for the extraction of PCDDs and PCDFs from fly ash samples. The introduction of benzene refluxing extraction brought a considerable time saving (ca. 19-31 h) in comparison with the conventional soxhlet extraction. In addition, the scale-down and combination of silica gel (1g) and alumina column (1g) gave sufficient purifications for analytes, and reducted remarkably the time in process of purification.
