A fluorescence based dual sensor for Zn²⁺ and PO₄³⁻ and the application of soft computing methods to predict machine learning outcomes

Abstract

Phenolphthalein-based Schiff base 3,3-Bis-{4-hydroxy-3-[(pyridine-2-ylmethylimino)-methyl]-phenyl}-3H-isobenzofuran-1-one (PAP) has been synthesized and used for selective fluorescence ‘turn on’ and ‘turn off’ sensing of Zn2+ and PO43- respectively. The limit of detection using 3σ...
