[0043] The second invention of the present invention provides a kind of preparation method of trisodium thiocyanate rapid detection test paper, at least comprises the following steps:
[0044] S1: Preparation of chromogenic agent: add inorganic metal salt reagent to distilled water (the distilled water described in the present invention is water that meets the requirements of GB / T 6682-1992) several times, and stir until the inorganic metal salt reagent no longer After continuing to dissolve, a mixed solution is obtained, and the mixed solution is filtered through a rapid chromatography qualitative filter paper to obtain a saturated inorganic metal salt solution;
[0045] S2: Preparation of color test paper: Soak uncut filter paper or rice paper in a color developer at room temperature, soak for 10 seconds at room temperature, take it out to dry and cut it into a suitable shape to obtain a color test paper.
[0046] Further, in order to improve the color developing effect, the...
