A voltammetric sensor based on NiO/CNTs ionic liquid carbon paste electrode for determination of morphine in the presence of diclofenac

Diclofenac as a nonsteroidal anti-inflammatory drug has been shown to decrease morphine consumption after operation in adults. The addition of regular doses of diclofenac may reduce the need for morphine after abdominal surgery. Therefore, in this study we describe a sensitive electrochemical sensor for simultaneous determination of morphine and diclofenac.88
