Eco-friendly spectrofluorimetric determination of fenbendazole in pharmaceutical, plasma, and milk samples using erythrosine B as a fluorescent probe
A simple, sensitive, and sustainable spectrofluorimetric method was developed to determine fenbendazole (FEN) based on its fluorescence-quenching interaction with erythrosine B (EB). Under the optimized conditions, FEN efficiently quenched the native fluorescence of EB (λex = 527 nm, λem = 544 nm). The decrease in fluo...
