Copper Based Organic Framework Modified Electrosensor for Selective and Sensitive Detection of Ciprofloxacin

The electrochemical detection of ciprofloxacin (CIP) using copper metal organic framework (Cu BTC) is reported. The glassy carbon electrode was used as a base electrode which was further modified with Cu BTC and differential pulse voltammetry technique was adopted for electrosensing. Under optimized conditions, a linear response for CIP was obtained in concentration range from 1×10−8 to 20×10−6 mol L−1 with a limit of detection of 0.47×10−9 mol L−1. Moreover, the proposed electrosensor showed acceptable reproducibility with 2.39 % relative standard deviation. Determination of CIP in tap water samples showed good recovery in range of 94.6–108 %.
