依据锑（Ⅲ）对铬（Ⅵ）─碘化钾氧化还原反应的诱导效应，建立了测定微量锑的诱导动力学光度法。本法测定锑（Ⅲ）的线性范围为０～３．０μｇ／ｍＬ，检测限为０．００５μｇ／ｍＬ。测定锡合金中锑含量，结果满意。
According to the inductive effect of antimony (Ⅲ) on chromium (Ⅵ) -potassium iodide redox reaction, an inducing kinetic spectrophotometry was established for the determination of trace antimony. The linear range of this method for the determination of antimony (Ⅲ) is 0-3.0 μg / mL with a detection limit of 0.005 μg / mL. Determination of tin content of antimony, the results are satisfactory.
