| 摘 要： | 主要研究了Al Ferron逐时络合比色法和2 7Al NMR法应用于聚合铝与有机高分子复合絮凝剂形态分布的测定 .结果表明 ,两种方法分别测定的Alb 和Al13 的结果具有一定的相关性 ;聚合铝与有机高分子复合后其形态分布发生了一定的变化 ,Alb(或Al13 )的含量有所降低 ,但仍是优势形态 ,Ala(或Al单)的含量基本保持不变 .

| Abstract: | The speciation characteristics of polyaluminum chloride\|organic polymer composite flocculants (PACP) were studied by Al\|Ferron timed complex colorimetric method and 27 Al\|NMR.The results showed:There is a certain relationship between Al\-b determined by Al\|Ferron method and Al\-\{13\} by 27 Al\|NMR;Al\-b(or Al\-\{13\}) of PACP as the priority species is a little less than that of PAC.On the other hand,the composition of PAC with organic polymer has little influences on Al\-a. |
