An On–off Supramolecular Fluorescence Switch for Detection of Pb2+ Ions and Vitamin C

Using the extract of pomegranate peel as a natural indicator for colorimetric detection and simultaneous determination of Fe3+ and Fe2+ by partial least squares–artificial neural network

“…30,31 Therefore, we can choose pomegranate peel as a spectroscopic sensor to detect iron. In the present work, in continuing our recent researches in the determination of biological and metal cations and anions, [32][33][34][35][36][37] we proposed a biocompatible, green, natural, selective, and sensitive spectroscopic detection and measurement of Fe 3+ and Fe 2+ . The method was successfully employed to specify and quantify the cited ions in real matrix water samples without complicated pretreatment using multivariate calibration methods.…”
