Abstract

The invention relates to a natural water sample in-situ suction filtration and solid-phase extraction integrated operation system and an operation method. The integrated operation system comprises a Buchner funnel, a suction filtration cylinder, an activating liquid bottle, a leacheate bottle, a first vacuumizing cylinder, a second vacuumizing cylinder, a solid-liquid extraction column, a rack, a four-way joint, a three-way joint and the like, wherein the four-way joint and the three-way joint are arranged in the rack. The integrated operation system disclosed by the invention is small and flexible in structure and convenient to carry, so that the integrated operation system can be carried to a natural water taking point and a site for water sample collection, water sample suction filtration and solid-phase extraction operation, the functions of field suction filtration and solid-phase extraction of natural water samples such as rivers, lakes or underground water are realized, the timeliness of sample treatment is ensured, and the data reliability and accuracy of water sample monitoring are improved. According to the operation method disclosed by the invention, water sample suction filtration and solid-phase extraction operations are completed at one time by utilizing one set of system, the operation steps are simple, the working efficiency is improved, and pollution hazards to the environment are avoided.

Description

technical field [0001] The invention relates to an in-situ suction filtration system for water samples, in particular to an integrated operating system for in-situ suction filtration and solid-phase extraction of natural water samples and an operating method thereof. Background technique [0002] Surface water such as rivers and lakes and groundwater contain many kinds of organic and inorganic components in nature, and these components even contain complex pollutants. At present, whether it is the analysis of constant substances in water samples or the analysis of key pollutants, water samples are usually collected in the laboratory and then pretreated. In the pretreatment work, there is a suction filtration link. The so-called suction filtration is to remove the impurity components contained in the water sample and realize the solid-liquid separation. However, for substances that are small in content and difficult to extract (such as antibiotics, hormones, etc.) in water ...
