A Novel Fluorescent Probe for the Determination of Aluminum Ions in Aqueous Samples

In this paper, the target compound, 4-hydroxy-3-[[(2-hydroxy-1-naphthalenyl)methylene]amino]benzenesulfonamide (hereafter referred to as HA), was synthesized via the reaction of 2-hydroxy-1-naphthaldehyde with 2-aminophenol-4-sulfonamide in an 86% yield. In methanol–water (<i>v</i>/<i>v</i>, 1:1, pH...
