This article describes a detailed comparison between the original BCR sequential extraction procedure, step 2 of which involves treatment with 0.1 mol l −1 hydroxylammonium chloride at pH 2, and the revised BCR procedure (step 2: 0.5 mol l −1 hydroxylammonium chloride at pH 1.5). An intermediate pro...
