title: A novel and efficient colorimetric chemosensor for detection and determination of biologically important ions in DMSO/H2O media using bromo pyrogallol red chemosensors with analytical applications.
abstract: An efficient colorimetric chemosensor with bromo pyrogallol red (BPR) as an easily available dye demonstrated a high chromogenic selectivity for Fe(3+) over other cations with detection limit of 5.1 μmol L(-1). The complex of Fe(3+) with BPR displayed ability to detect of up to 4.4 and 25.6 μmol L(-1) for acetate (AcO(-)) and benzoate ions (BzO(-)) in DMSO/H(2)O (9:1 v/v) media respectively over a large number of other anions. Both processes proceeded with distinct visual color changes in DMSO/H(2)O (9:1 v/v). The linear dynamic ranges for the determinations of Fe(3+), AcO(-) and BzO(-) were 2.5-24.0, 2.5-20.5 and 28.0-42.0 μg mL(-1) respectively. This chemosensor was successfully applied for the determination of Fe(3+) and of carboxylate anions in environmental samples. This is the first article of a chemosensor capable of detecting both Fe(3+) and anions (AcO(-) and BzO(-)) using single detection method in a single cell.
