摘要: Abstract A novel surfactant sensitized fluorescent chemosensor for safranine T (ST) based on calixarene-1,3-diacyl hydrazone (CADH) in sodium dodecyl sulfate (SDS) medium was investigated. The fluorescence intensity of CADH quenched by ST due to the formation weak inclusion complex (ST-CADH), and quenching (Δ F = − ST-CADH ) SDS. Under optimal conditions, linear range calibration curve determination 0.02–3.00 μg/m detection limit estimated 0.015 μg/mL with RSD 2.2% ( n = 3, c = 1.0 μg/mL). mechanism discussed type, effect. This method has been applied real samples satisfactory results.
