Chlordane is one of the persistent organic pollutants which were decided to be controlled globally first by the UNEP due to its physical and chemical stability, recalcitrant degradation under natural conditions and tending to accumulate in organisms. It had been proved that Chlordane may cause cancer, malformation and mutation, so research of elimination of Chlordane in the environments is of great significance to the health and sustainable development of humankind. Chlordane was the research object in this paper.
