A kind of spill-proof test paper box for rapid detection of various heavy metal ions

Abstract

The invention discloses an anti-overflow type multi-heavy metal ion rapid detection test paper box. The anti-overflow type multi-heavy metal ion rapid detection test paper box comprises a shell and a press cover matched with the shell, wherein the shell is of a rectangular solid structure with open top, a buffer air cushion is arranged in the shell, an adhesive sticker layer is arranged on the buffer air cushion, and is sequentially provided with limiting strips against each other in an end-to-end way, a urease immobilized cellulose acetate membrane, water soluble release paper, urea and cresol red immobilized developing and water-absorbing filter paper and water-absorbing paper from left to right, a sample solution dropping-in hole is formed in the position at which the press cover corresponds to the cellulose acetate membrane, a liquid storage cavity is formed in the press cover, and is communicated with the sample solution dropping-in hole by virtue of an overflow channel, and an observation window is formed at the position at which the press cover corresponds to the developing and water-absorbing filter paper. The anti-overflow type multi-heavy metal ion rapid detection test paper box is simple in structure, does not overflow and is easy to use and carry, developing is rapid and uniform, the detection efficiency is high, and the detection results are accurate.

Description

technical field [0001] The invention relates to the technical field of detection of heavy metal ions, in particular to an overflow-proof test paper box for rapid detection of various heavy metal ions. Background technique [0002] Heavy metals are one of the important environmental pollutants, which can accumulate in living organisms and enter the human body through channels such as the atmosphere, drinking water, and food, causing serious harm to human health, including carcinogenicity, teratogenicity, and mutagenicity. . Therefore, the detection of heavy metals, especially the rapid detection of heavy metal residues in agricultural products, food, and drinking water, has become one of the focuses of public attention. [0003] Traditional heavy metal detection methods mainly include atomic absorption spectrometry, atomic emission spectrometry, atomic fluorescence spectrometry, anodic stripping voltammetry, ion chromatography, spectrophotometry, etc., but most of them have ...
