Bi-component sensing platform for the detection of Cd²⁺, Fe²⁺and Fe³⁺ ions.

ABSTRACT: The ability of N-(1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)isonicotinamide (naphydrazide) or 2,6-pyridinedicarboxylic acid (2,6-H₂pdc) individually or as a bi-component system in distinguishing and detecting Fe³⁺ or Fe²⁺ and Cd²⁺ ions was investigated. The use of these molecules as single or bi-component analytes in absorption or emission spectroscopy studies showed that under specific conditions each had their own merits for specific purposes. UV-visible spectroscopic studies of 2,6-H₂pdc for assessing the interactions with ferrous and ferric ions showed characteristic distinctions. The detection limit for Fe³⁺ analysed through UV-visible spectroscopy using naphydrazide was 0.46 μM, whereas it was 1.2
