Electrochemical determination of acetaminophen by a sensor based on samarium ferrite and carbon nitride

Currently, the detection of drugs in biological samples is a lengthy and time-consuming process that requires the use of expensive equipment. Acetaminophen is an effective antipyretic agent and a painkiller. Detection of acetaminophen in biological samples is important due to widespread use of this drug for medicinal purposes. In this paper an electrochemical approach is considered for the detection of acetaminophen in water. The use of a carbon paste electrode modified with SmFeO3/g-C3N4 composite material makes determination easy and fast, thanks to the best combinations of properties. The detection limit of acetaminophen for the proposed electrode is 500 nM, the maximum is 230 µM
