| 摘 要： | Fe^3＋和Mn^2＋分别在不同pH下与5-Br-PADAP形成有色络合物．显色条件实验表明，Fe^3＋和Mn^2＋在单一组分的不同缓冲溶液体系中不能与显色剂同时显色．通过研究，提出选用乙酸一乙酸钠、硼砂一盐酸双缓冲溶液体系，成功地解决了Fe^3＋和Mn^2＋同时与5-Br-PADAP显色的问题，为进行汽油中的铁、锰含量的分光光度同时测定提供了基本条件．在此基础上，应用化学计量学方法对实验结果进行了解析．

| Abstract: | The content of Fe~(3+) and Mn~(2+) can be determined by photometric method with 5-Br-PADAP as color reagent in different pH solution.Experimental results indicate that Fe~(3+) and Mn~(2+) can not be simultaneously determined by photometric method with 5-Br-PADAP as color reagent in single buffer solution.We have applied acetic acid-sodium acetate and sodium tetraborate-hydrochloric acid two kinds of buffer solution to solve the problem successfully.So,it can make a condition simultaneous determination of Fe Mn in simulated-gasolene.Spectral datum is analyzed by chemometrics method.Prediction result of sample is reduced remarkably with desired results. |
