Development and validation of an eco-compatible UV-Vis spectrophotometric method for the determination of Cu²⁺ in aqueous matrices.

ABSTRACT: Cu²⁺ are ubiquitous ions in the ecosystem and are responsible of serious environmental pollution. Indeed, the development of sensitive methods for Cu²⁺ detection is an urgent demand. In this work, we proposed a new spectrophotometric method for Cu²⁺ determination in different water matrices (distilled water, drinking water, wastewater, and river water). The method employs a bio-based organic ligand namely tetrasodium iminodisuccinate (IDS) able to form a stable complex with the analyte with a maximum absorption at 710 nm. Within the linear range of 6.3-381 mg L^-1, the limit of detection (LOD) was determined to be as 1.43 mg L^-1. Moreover, the recovery data of the spiked analysis of drinking/river/wastewater water samples were also sati
