Resumo: | Generation of volatile species (CVG) from Fe2+, Fe3+, Cr3+, CrO4²ˉ, Mn2+ and MnO4ˉ ions by reaction with NaBH4 reductant in HCl, CH3COOH and citric acids using gas-liquid phase separation system and inductively coupled plasma atomic emission spectrometry detection (ICP OES) was reported. The optimized conditions were obtained using low concentrations of HCl (0.05‑0.075 mol L‑1) and NaBH4 (0.25-1.0% (m/v)). Volatile species were more effectively generated for lower oxidation state of the analytes. Detection limits of 10, 25 and 66 ng mL-1 were achieved for Mn2+, Fe2+ and Cr3+, respectively. |
