Abstract

The invention relates to a method for detecting drugs by combining liquid-phase extraction and fluorescence sensing technologies. The method comprises the steps of firstly, treating a test sample in aliquid-phase extraction mode to ensure that the drugs can be enriched, purified and extracted, and the chemical structure of the drugs in the sample can be prevented from being damaged; and therefore, when the drugs are further detected on the basis of a fluorescence sensing technology, outputting an accurate detection result. Moreover, the fluorescence sensing technology has the advantages of high sensitivity, good selectivity, rich response signals, simplicity in operation, simple detection conditions, lower requirements on instruments and the like, and compared with a traditional detectionmethod, the fluorescence sensing technology is easier to miniaturize devices and can be used for quickly detecting the drugs in real time.

Description

technical field [0001] The invention relates to the field of drug detection, in particular to a method for combined detection of drugs by liquid phase extraction and fluorescent sensing technology. Background technique [0002] Drugs include traditional drugs and new drugs. Traditional drugs include opium, morphine, heroin, marijuana, cocaine and other drugs. New drugs include methamphetamine, ecstasy, and K powder. Whether it is a traditional drug or a new type of drug, it is highly toxic and will damage the central nervous system of the user, consume a large amount of physical strength of the user, and endanger the heart and brain tissue. Excessive drug use can cause serious harm to the human body and even lead to death. Drugs not only bring harm to users, but also bring a series of violent crimes, which seriously endanger the security of the country and the people. Strong supporting evidence. [0003] Ordinary drug testing, such as the test results obtained through dru...
