Specific embodiment
The present invention provides a kind of supermolecule kits and method for Rapid identification detection diquat dibromide, below with reference to tool
The present invention will be further described for body embodiment.
One, reagent
Safranine T (ST), methylene blue (MB) and hematoxylin (HT), purchase is in Aladdin；Carboxymethyl-beta-cyclodextrin purchase
In Shandong Binzhou Zhi Yuan Biotechnology Co., Ltd；Diquat dibromide standard specimen was bought in Inst. of Environment Protection & Scientific Research Monitor, Ministry of Agric, used time
The working solution of required concentration is diluted to ultrapure water.
Two, the preparation of supermolecule kit
It takes 0.0088g ST to be placed in 25mL volumetric flask and obtains the ST solution of 0.001mol/L, 0.0093g MB is placed in 25mL appearance
Measuring bottle obtains the MB solution of 0.001mol/L, and 0.0850g CM- β-CD is placed in 50mL volumetric flask and obtains the CM- β-of 0.001mol/L
CD solution.CM- β-CD the solution of the ST solution and 250 μ L that take 125 μ L is placed in 1mL centrifuge tube, and being uniformly mixed is reagent 1；It takes
CM- β-CD the solution of the MB solution of 125 μ L and 250 μ L are placed in 1mL centrifuge tube, and being uniformly mixed is reagent 2.
