A novel fluorescent sensor for fast and highly selective turn-off detection of Fe3+ in water and pharmaceutical samples using synthesized azopyrazole …
Highly selective spectrofluorimetric detection of Fe 3+ ions in acidic medium is developed
using novel fluorescent sensor, namely 4-(2-(3-Methyl-5-oxo-1-tosyl-1H-pyrazol-4 (5H)-
ylidene) hydrazinyl)-N-(pyrimidin-2-yl) benzenesulfonamide (PHBS-sensor), which gives an
selective fluorescence quenching response at λ Emission 379 nm. The factors affecting
fluorescence detection process, such as the pH, solvent type, buffer type, probe
concentration, reaction time and co-existing ions were systematically studied and optimized …
