This invention discloses a soil chloride ion detection pretreatment device, its usage method, and a filter paper preparation method, relating to the field of laboratory equipment technology. The device includes a funnel placement rack with a double-compartment funnel inserted inside. Eight evenly distributed structural support ribs are fixedly installed on the inner wall of the double-compartment funnel. Folded composite filter paper and a nylon support mesh are placed sequentially on the structural support ribs. The upper layer of dilute nitric acid is used to wash away chloride from the activated carbon fiber layer, efficiently adsorbing colored substances such as humus and organic matter in the soil extract. This results in a clear and transparent filtrate, eliminating the interference of deep yellow and brown to the brick-red endpoint of the silver nitrate titration method. The endpoint is clearly distinguishable, and the chloride ion recovery rate is stabilized at 92.0%–105.0%. This solves the problem of the lack of a decolorization step in the silver nitrate titration method, leading to a blurred endpoint and a detection error of over 20% caused by high-chroma soil extract.
