Abstract

The invention discloses a rapid testing card for heavy metal mercury and a testing method thereof. The structure of the testing card includes a base board, absorption wafers and a cover film successively from bottom to top. At least one wafer for absorbing color-developing agents and at least one wafer for absorbing urease are respectively fixed on the base board, and the wafers are not overlapped mutually. The use amount ratio of the urease and the color-developing agents absorbed by the wafer per unit area is 3U: (1.6-3.2mL), and the color-developing agents contain components of, by mass, 0.05% to 2.5% of phenol red and 0.8% to 2% of urea. The testing card can test the content of mercury larger than or equal to 0.2 mg / L rapidly, accurately and conveniently; the test card is low in cost, simple and convenient to operate, short in testing time, in no need of professionals, sensitive in reaction and easy to observe and interpret; and the testing card is non-toxic and harmless and cannot cause environment pollution.

Description

technical field

[0001] The invention relates to heavy metal detection, in particular to a heavy metal mercury rapid detection card and a detection method thereof. Background technique

[0002] With the development of industry, water quality and soil are seriously polluted by heavy metals, which will have adverse effects on human health. The current heavy metal detection needs to be digested by strong acid, high pressure, and high temperature samples, and then tested by atomic absorption instruments and other equipment. For heavy metal detection samples, there are many pre-treatment procedures, long detection cycles, professional equipment and professional operators are required, and waste liquids pollute the environment. The problem is that providing a method and / or product for rapid detection of heavy metals is very important to meet the current market demand for rapid on-site heavy metal detection and screening of a large number of samples, and to fill the gaps at home and...
