Description

technical field

[0001] The invention relates to the field of materials, in particular to a graphene oxide / molecularly imprinted filter membrane for detecting propranolol and its preparation and application. Background technique

[0002] Propranolol is one of the most commonly used beta adrenergic blockers for the treatment of arrhythmia, angina pectoris, high blood pressure and other diseases. After taking or injecting, most of it is digested in the human body, but a small part is still discharged into the environment. With the increase of usage, more and more rivers and lakes have found the existence of propranolol. When propranolol enters the human body, it can completely inhibit heart function, induce and aggravate bronchial asthma, and cause adverse reactions such as intermittent claudication.

[0003] For propranolol, currently commonly used detection methods include high performance liquid chromatography, gas chromatography-mass spectrometry, etc. These methods genera...
