KSCN分光光度法测定Fe^(3+)条件研究

Study on the Determination of Fe^(3+) by Potassium Thiocyanate Spectrophotometry

应用KSCN分光光度法对Fe^(3+)含量测定条件进行了优化。探讨了最佳显色条件和测定条件,并讨论了共存离子对Fe^(3+)测定的影响。该法操作简单、准确度和精密度高且选择性好,适合于水溶液中Fe3+含量的测定。

The potassium thiocyanate spectrophotometric method was used to optimize the content of ferric iron. The best color conditions and measuring conditions were discussed. The influcence of coexistent irons also was studied. This method is simple, accuracy and precision, and is suitable for the determination of ferric iron in water.
