Rhodamine B detection device based on mobile phone and detection method thereof

Abstract

The invention relates to a Rhodamine B detection device based on a mobile phone and a detection method thereof. The Rhodamine B detection device and the detection method thereof are used for detectingwhether an illegal additive of Rhodamine B which has serious harm to human bodies is contained in food or not. The detection device comprises a lens, a near-ultraviolet LED light source, a clamp part, a main control circuit board, a bluetooth chip connected to a mobile phone and a rechargeable lithium battery. The device is matched with an APP of the smart phone, an image is acquired and analyzedby combining advanced technologies such as the internet and the big data analysis with the camera shooting function of the mobile phone, so that whether a sample contains the Rhodamine B or not is obtained. The device and the method have the advantages of being easy to operate, convenient to carry, high in testing precision and the like.

Description

technical field [0001] The invention relates to a mobile phone-based Rhodamine B detection device and a detection method thereof, which are used to detect whether food contains Rhodamine B, an illegal additive that is seriously harmful to the human body, and the device can also be used as a banknote detection device to identify the authenticity of banknotes . Background technique [0002] Rhodamine B (Rhodamine B), also known as rose red B, basic rose essence, stamen red B, commonly known as flower pink. It is a synthetic basic fluorescent dye. It is mainly used for industrial dyeing of paper making, paint making, textile, leather and porcelain; at the same time, it is also a common analytical reagent, widely used in environmental protection, mining, steel, medicine and other fields, and can also be used as a cell fluorescence staining agent in the laboratory . It was once used as a food additive, but experiments have proved that rhodamine B can cause cancer, and it is no...
