| Abstract: | A multi-step extraction with dichloromethane was used for extracting dyes presented in secondary effluent of municipal wastewater treatment plant. After purification and pre-separation of the extract on a silica gel column, seven dyes were tentatively identified by reversed-phase high performance liquid chromatography and checked with thin-layer chromatography. Subsequently, the concentrations of these dyes were quantitatively determined by HPLC. |
