Abstract

The invention discloses a portable soil heavy metal ion rapid qualitative determination device and determination method. The device includes a sample cylinder, including a detection reagent sample area, a soil sample area and a qualitative color development area arranged in sequence from top to bottom, and a detection reagent sample area. It is threadedly connected with the soil sample area; the upper part of the detection reagent sample area is provided with a plurality of reagent injection ports, and the bottom plate of the detection reagent sample area is threaded with the soil sample area; the bottom plate of the detection reagent sample area is provided with a plurality of first reagent circulation The detection reagent sample area is provided with a reagent pusher for pushing the reagent; the lower part of the soil sample area is fixed with the qualitative color development area; a baffle is arranged between the soil sample area and the qualitative color development area. A plurality of second reagent circulation ports are opened on the board, and the bottom board of the qualitative color development area is screwed to the side wall thereof. The detection process of common pollutants in soil is cumbersome, the required equipment is professional, the detection process is cumbersome, professional and difficult to promote.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a portable soil heavy metal ion rapid qualitative determination device and a determination method. Specifically, it refers to a convenient and portable device that can quickly and effectively detect the presence of certain heavy metal ions in soil. Background technique [0002] The current environment is facing serious pollution problems brought about by the development of industry, agriculture, and service industries. The problem of soil pollution is more serious and prominent. Soil pollution will bring polluting elements into plants, and in the metabolism of crops It is enriched and gradually enriched in the human body in the food chain, which brings great safety hazards to human individuals, and some heavy metals will affect the health of their next generation, leading to serious problems such as deformed babies. The detection of known pollutants...
