High-resolution continuum source graphite furnace molecular absorption spectrometry has been applied for sulfur determination in diesel fuel. The sharp rotational lines of the carbon monosulfide molecule (formed during the vaporization step) were used to measure the absorbance. The analytical line at 258.056 nm was monitored using the sum of three...
A slurry sampling procedure for arsenic speciation analysis in baby food by arsane generation, cryogenic trapping and detection with atomic absorption spectrometry is presented. Several procedures were tested for slurry preparation, including different reagents (HNO3, HCl and tetramethylammonium hydroxide - TMAH) and their concentrations, water bat...
Este estudo avalia a presença e os níveis de hidrocarbonetos policíclicos aromáticos (HPAs) em amostras comercias de pimentas, usando extração sob ultrassom acompanhada de etapas de cleanup e determinação por cromatografia gasosa acoplada à espectrometria de massas. Foram avaliados os 16 HPAs listados como contaminantes ambientais prioritários pela...
