Device and method for rapidly detecting basic orange, acid orange and basic tender yellow

Abstract

The invention discloses a device for rapidly detecting basic orange, acid orange and basic tender yellow. The device comprises a reagent bottle filled with extraction reagent, a reagent bottle filled with a color developing agent, a reagent bottle filled with diluent, colorimetric identification cards, a filter and a transfer pipette, and the colorimetric identification cards comprise three sets of double color cards which are used for indicating existence of basic orange, acid orange and basic tender yellow respectively. The invention further discloses a corresponding method for rapidly detecting basic orange, acid orange and basic tender yellow. According to the device and method for rapidly detecting basic orange, acid orange and basic tender yellow, the color developing agent and the diluent are sequentially added, comparison with color of the color cards at the left side and the right side of a colorimetric card set is made, and according to the matching condition of solution color, under the action of the color developing agent and the diluent, of a sample to be detected with the color at the left side of the colorimetric card set and the color at the right side of the colorimetric card set, whether certain pigment in basic orange, acid orange and basic tender yellow is contained or not is judged; rapid screening can be achieved, operation is simple and efficient, and the limitation that coloring agents such as basic orange, acid orange and basic tender yellow in traditional colorimetric analysis are similar in color, so that the coloring agents are difficult to differentiate effectively and complex equipment is needed to be introduced is avoided.

Description

technical field [0001] The invention relates to a device for rapid detection of basic orange, acid orange and basic bright yellow and a detection method thereof, belonging to the field of analytical chemistry. Background technique [0002] Azo prohibited dyes are highly carcinogenic, highly toxic and harmful, and have been listed as key monitoring objects by countries all over the world. Non-edible industrial dyes / colorants such as basic orange are used in violation of regulations in the production process, seriously endangering public health and industry integrity. Rapid and accurate monitoring of colorant residues such as basic orange and acid orange in food has become the focus of attention of the whole society. [0003] The determination methods of colorants such as basic orange and acid orange mainly include spectrophotometry and chromatography. Using colorimetric detection, the analysis of basic orange and acid orange colorants is simple and fast. Using high-perform...
