摘要
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。
A kinetic spectrophotometric method for determination of antimony had been proposed based on the inductive effect of antimony(Ⅲ) on the chromium(VI)-iodide redox reaction. The calibration graph is linear for 9￣3.Oμg/mL Sb (Ⅲ), and the detection limit is 0.005μg/mL.The content of antimony in the tin based alloy had been determined with the proposed method. The results are satisfactory.
