Determination of 1,2-dichlorobenzene in waste water by GC-MS

Chlorinated benzenes: Organachlorine compounds are chlorinated hydrocarbons or compounds containing chlorocarbons. There are 12 chlorinated benzene compounds. Monochloro benzene (MCB), dichloro benzenes (DCB), trichloro benzenes (TCB), tetrachloro benzenes (TeCB), pentachloro benzene (PCB) and hexachloro benzene (HCB). Hexachlorobenzene is used as an insecticide in the UK, while all other chlorobenzenes are mostly used as intermediates in the manufacture of pesticides and dyes. (Harrison N., 2001). In this study, gas chromatography mass spectroscopy (GC-MS) method was used for the determination of 1,2-dichloro benzene, which is frequently used among dichlorobenzenes, in wastewater. The method is based on the method of taking 1,2-DCB, which is likely to be found in the wastewater used in paint production, to the organic phase with the help of dichloromethane (DCM) and its determination by GC-MS. It is aimed to determine whether there is 1,2-DCB in wastewater, if so how much.
