Efficient removal of the organochlorine pesticide and heavy-metal residues inEpimedium brevicornum Maxim by supercritical fluid extraction

A method involving depuration of 12 organochlorine pesticides (OCPs) and 7 heavy metals fromEpimedium brevicornum Maxim was developed using supercritical fluid extraction (SPE). The pesticides in the study consisted of α, β-, γ-, and δ-Benzene hexachloride, Pentachloro-nitrobenzene (PCNB), Pentachloroaniline (PCA), Heptachlor (HEPT), Methyl -pentachlorophe-nyl sulfide (MPCPS), pp’-DDE[1,1-dichloro-2, 2-bis (p-chlorophenyl) ethylene], op’-DDT...
