原始语种摘要: Abstract(#br)This work presents a novel approach for simultaneous determination of butylated hydroxyanisole (BHA) and propyl gallate (PG) in a very interfering environment by combining the sensitivity of molecular fluorescence and the selectivity of the second-order calibration method. The excitation–emission fluorescence matrix data are processed by applying the second-order calibration method based on the self-weighted alternating normalized residue fitting (SWANRF) algorithm. The limits of detection (LOD) were 1.2–1.3ng/ml for BHA and 2.2–2.9ng/ml for PG. The recoveries from spiked cosmetics samples are in the ranges 95.7–103.9% for BHA and 95.9–105.7% for PG. The proposed method avoids preconcentration and elution procedures, so it considerably...
