A fast, simple, and reliable chemical method for tellurite quantification is described. The procedure is based on the NaBH(4)-mediated reduction of TeO(3)(2-) followed by the spectrophotometric determination of elemental tellurium in solution. The method is highly reproducible, is stable at different pH values, and exhibits linearity over a broad range of tellurite concentrations.
描述了一种快速、简单、可靠的亚碲酸盐定量化学方法。该方法基于 NaBH(4)介导的 TeO(3)(2-)还原,随后在溶液中进行元素碲的分光光度测定。该方法重现性好,在不同 pH 值下稳定,且在较宽的亚碲酸盐浓度范围内呈线性。
