| 中文摘要 |
| 采用改进的 Al-Fe-Ferron逐时络合比色法和酸滴定实验研究了典型羟基聚合铝铁(nAl/nFe=9∶1,5∶5)溶液的形态转化 .结果表明 ,羟基聚合铝铁的形态转化主要由 nAl/nFe值、碱化度和熟化等因素决定 ;羟基聚合铝铁的形态转化特征是优势形态之间的转变 ;当nAl/nFe>5∶5,随碱化度的升高 ,[Al+Fe]a和 [Al+Fe]b 2类形态逐渐占优势 ;随nAl/nFe值的减小 ,[Al+Fe]a和 [Al+Fe]c增加 ,而 [Al+Fe]b 减少 .讨论了羟基聚合铝铁的形态转化规律 . |
| 英文摘要 |
| The species transformation of typical hydroxyl polymeric aluminum ferric chloride(HPAFC)(nAl/nFe=9∶1,5∶5)were studied with improved Al Fe Ferron time colorimetric procedure and acid titration experiments.The results showed that the species transformation mainly depends upon nAl/nFe,basicity(B)and ageing.dominant species of HPAFC transform each orther directly.When nAl/nFe>5∶5,[Al+Fe]a and [Al+Fe]b become dominant species with increasing of basicity.[Al+Fe]a and [Al+Fe]c increase but [Al+Fe]b decrease with decreasing nAl/nFe.The species transformation model of HPAFC was suggested |
