| 摘 要： | 本文主要探讨了铝的水解聚合形态的两种测定方法，即Ａ１－Ｆｅｒｒｏｎ逐时络合比色法和＾２７Ａ１ ＮＭＲ核磁共振法。扼要地说明了Ａ１－Ｆｅｒｒｏｎ逐时络合比色法中不同比色－缓冲的配制及其测定结果，以及＾２７Ａ１ ＮＭＲ法中大、小管测量方法及其测定结果。最后对这两种铝的水解聚合形态分析方法的相关性作了对比。

| Abstract: | This paper studied two kinds of analysis methods for aluminum species resulted in hydrolysis-polymerization processes: Al-Ferron timed complex colorimetric method and 27Al NMR spectroscopy method. For the colorime-tric methodd, the different colorimetric reagent preparation methods were compared. Some differences were fined between their determined results, but the combined method can be used as a simplified procedure. For the 27A1 NMR method, the big and small tube measure methods were compared. The small tube method was more accurate. Then the result of two kinds of analysis methods were compared and disscussed. The Al13 of 27A1 NMR results were compared to the Alb of colorimetric method. |
