A detection cu 2+ Fluorescent probes, preparation methods, and preparation and use methods of fluorescent test strips

Abstract

The invention provides a Cu<2+> detection fluorescence probe, a preparation method of the Cu<2+> detection fluorescence probe, and a use method and preparation of a fluorescence test paper strip, relates to the Cu<2+> detection fluorescence probe, and the preparation method and the use method of the Cu<2+> detection fluorescence probe, and aims at solving the technical problems that the existing Cu<2+> detection cannot realize the field detection due to instrument limitation and higher cost; during the Cu<2+> detection by using a fluorescence probe method, the anti-interference capability of amain body on metal ions is poorer. The fluorescence probe has a structure formula shown in the description, and is prepared from 2-(2-aminophenyl)phenanthro-imidazole and pyridine-2-formaldehyde through reaction. The Cu<2+> detection fluorescence probe can be prepared into a solution; next, qualitative filter paper is sheared into strips to be soaked into the solution; after the drying, the fluorescence test paper strip for detecting the Cu<2+> can be obtained. Whether the sample contains Cu<2+> or not can be judged through watching whether the color of the test paper strip becomes bright light purple from the dark purple or not. The Cu<2+> detection fluorescence probe synthesis method is simple; the cost is low; the steps are simple; the yield is as high as 70 to 98 percent; the probe can be used for detecting the Cu<2+> in the water system environment.

Description

technical field [0001] The invention belongs to detecting Cu 2+ technical field involving the detection of Cu 2+ Preparation and Detection of Fluorescent Probes for Cu 2+ Preparation of fluorescent test strip and method of use thereof. Background technique [0002] Copper is an indispensable micronutrient element for human health. It is a constituent element of hemocyanin in the human body. It is very important for the development and function of the blood, central nervous system and immune system, hair, skin and bone tissue, as well as the brain, liver and heart. important influence. However, Cu present in excess 2+ It has adverse effects on organisms and the environment, such as maintaining metabolism in the human body, liver cirrhosis, liver ascites, etc., so Cu 2+ It is very important to carry out qualitative and quantitative detection. Traditional Cu 2+ Detection methods include ion plasma mass spectrometry, atomic absorption spectrometry, atomic emission spectro...

Problems solved by technology

[0009] The present invention is to solve the existing laboratory traditional method to detect Cu 2+ Due to the limitation of the instrument and the high cost, the technical problem of real-time on-site detection cannot be achieved; the use of fluorescent probe method to detect Cu 2+ When the main body does not have specificity in the identification of metal ions, the technical problem of poor anti-interference ability; making Cu 2+ The process of fluorescent test paper is complex and cumbersome, and the technical problem is high cost
