Novel use of calmagite as a fast and easy colorimetric anion chemosensor and solid-state sensor for carbonate ion in running water

This experiment studies the use of an available azo dye, calmagite (CAL), for the recognition of carbonate ion in running water. The linear range of carbonate, derived from the results of this simple, selective, sensitive and rapid determination, was 1.2 × 10 −8 -5.4 × 10 −6 mol L −1 with the detect...

Description
Summary:This experiment studies the use of an available azo dye, calmagite (CAL), for the recognition of carbonate ion in running water. The linear range of carbonate, derived from the results of this simple, selective, sensitive and rapid determination, was 1.2 × 10 −8 -5.4 × 10 −6 mol L −1 with the detection limit of 1.6 × 10 −8 mol L −1 . In the examined cases, the coexisting cation, anions and weak acids (NO 3 − , NO 2 − , SO 4 2− , SO 3 2− , HSO 3 − , OAc − , I − , Br − , F − , Cl − , SCN − , CO 3 2− , HCO 3 − , H 2 PO 4 − , HPO 4 2− , Cit 3− ), (Ascorbate, K + , Na + , Mg 2+
