title: Colorimetric detection of copper and chloride in DMSO/H₂O media using bromopyrogallol red as a chemosensor with analytical applications.
abstract: We report bromopyrogallol red (BPR) as an easily available dye for detection of copper and chloride with distinct visual color changes in DMSO/H(2)O (9:1 v/v). The chemosensor has a high chromogenic selectivity for Cu(2+) over other cations with detection limit of 0.07 μg mL(-1). The obtained complex of Cu(2+) with BPR displayed ability to detect Cl(-) up to 0.79 μg mL(-1) in DMSO/H(2)O (9:1v/v) media over a large number of other anions. The linear dynamic ranges for the determinations of Cu(2+) and Cl(-) were 0.53-14.60 and 6.00-36.00 μg mL(-1), respectively. This receptor was successfully applied for the determination of Cl(-) and Cu(2+) in water samples.
