The invention discloses a colorimetric card for rapidly detecting the concentration of hesperidin as well as a manufacturing method and application of the colorimetric card, relates to the technical field of hesperidin concentration detection, and provides a colorimetric card for rapidly detecting the concentration of hesperidin, which is a set of color development degrees obtained after a hesperidin solution with a certain gradient concentration is subjected to color development under ultraviolet light in a fluorescent support medium. The colorimetric card can be compared with the color development condition obtained after the color development of a hesperidin solution extracted from the dried orange peel to be detected in a fluorescent support medium and under ultraviolet light, the concentration interval range of the hesperidin solution is rapidly obtained, and then the quality of the dried orange peel is judged.

The invention provides a laboratory small-scale test device for ozone water treatment of an ozone catalyst. The laboratory small-scale test device comprises a bottle cap combined gas inlet pipe, a zeolite gas dispersing small ball, an organic glass cylindrical pipe with a circular truncated cone bottle opening, a zeolite filter plate and a circular truncated cone base, the size of an opening in the lower end of the bottle cap conforms to that of a circular truncated cone bottle opening in the top of the organic glass cylindrical tube, and good air tightness in the device is guaranteed. The gas inlet pipe is in a right-angle bent shape and penetrates through the center of the bottle cap. Ozone enters the zeolite gas dispersing ball with the micropore structure at the lower end through a left gas inlet in the upper end of the gas inlet pipe. The organic glass cylindrical tube with the circular truncated cone bottle opening is filled with an ozone catalyst, and the zeolite filter plate loaded ...
