Abstract
Natural and anthropogenic sources produce mainly metal ions which can be accumulated in sediments that have a significant environmental impact on local areas, especially for their river water quality. The environmental analysis applies chemical sensors having the inherent ability to detect in real-time analytes as cations, anions, or small molecules in water systems. In this regards, the aim of our work was the development of a simple and rapid electrochemical method for selectively copper determination in water samples using non-toxic and easy degradable peptide molecules such as a hemorphin analogue. Analytical characterizations as sensibility, linear dynamic range (LDR), the limit of detection (LOD), and limit of quantification (LOQ) have been also discussed. The results revealed that the peptide sensor provided electrochemical and sensing excellent response with a low limit of detection (0.188 ng ml−1). The precision of the method proposal evaluated by the relative standard deviation is 0.7%.
