The utility model provides a collection system of chlorion deposition survey in atmospheric environment, its characterized in that: chlorion collection system including the receiving flask and in inserting the receiving flask, the receiving flask includes the bottle and contains the catch tray of solution that the catch tray is installed the lower part of bottle, chlorion collection system includes post core, draw -in groove, clamp and is pipy gauze, is pipy gauze cover and establishes on the post core, and the draw -in groove is sealed with the gauze card jail of post core top, the clamp is fixed the gauze at post core middle part and insert the bottleneck, in the free end solution that dipes in the bottle flagging naturally of gauze. Design into the tubulose with the gauze area in this device, reduce when having increased the area because the influence of lacing film orientation production, with the post core branch center fretwork that the gauze covered, the air current of being convenient for to pass through flows, reduces the error owing to the turbulent flow of the air current around the collector produces, the volume of increase receiving flask and the area of catch tray are avoided producing the chlorion loss and are caused measuring error.
