A Bibliographic Review of Diclofenac Sodium Determination with Electrochemically Modified Sensors in Different Biological, Pharmaceutical, and water Sources

Abstract

Abstract Diclofenac sodium (DS) attracts the interest of researchers because it is one of the most prevalent pharmaceuticals in aqueous matrices and has the potential to harm aquatic life. However, most of the techniques used to analyze it are expensive and require a highly trained professional to perform them. On the other hand, there is the possibility of testing DS with electrochemical sensors. They are currently available for determining contaminants in different samples (tablets, blood, urine), but only a few articles analyze DS in wastewater. This is how the selection of articles for the review was organized by the type of modifier used in the working electrode. In addition, recent improvements in DS detection using electrochemical techniques in pharmaceutical formulations, biological fluids, and environmental materials were provided and discussed, along with a brief description of the results and methods used in the development publications.
