PURPOSE: A pretreatment apparatus for analyzing remaining heavy metals in soil is provided to have stability because a soil pretreatment work is performed in a housing which provides a closed space for analyzing heavy metals remaining in the soil. CONSTITUTION: A pretreatment apparatus for analyzing remaining heavy metals in oil comprises: a housing (10) which comprises an upper door and a lower door at the upper and lower portions, respectively and selectively provides a closed space by the upper and lower doors; a sample heating device (20) which comprises a lifting and lowering device (22) mounted on the bottom inside of the housing and a heating block (24) mounted at the lifting and lowering device to be lifted and lowered and heats a sample at a predetermined temperature; a sample tube mounting unit (50) which comprises a tube transfer rack (52) on which sample tubes (30) containing soil to be treated are contained and is configured to draw the tube transfer rack to the outside when the lower door is open; and a condenser mounting unit (60) which comprises a rack (62) for condensers and a connection device (64). The condensers (40) are placed on the rack and are connected to each sample tube. The connection device selectively connects each condenser to the sample tubes. |
