摘　　要：采用Ferron逐时络合比色法将铝铁作为一个整体对自制无机-有机复合絮凝剂NFAC-PEM/AM中[Al+Fe]形态分布进行表征,并考察了反应条件对[Al+Fe]形态分布的影响。结果表明:随着m(NFAC)∶m(PEM/AM)减小,复合体系中[Al+Fe]a含量基本保持稳定,[Al+Fe]b含量逐渐减少,而[Al+Fe]c含量却增大;随着pH值增大,复合体系中[Al+Fe]a含量显剧减少,[Al+Fe]b和[Al+Fe]c含量均逐渐增加;随着反应温度升高,复合体系中[Al+Fe]a含量有所减少,[Al+Fe]c含量适当增加,而[Al+Fe]b含量基本保持稳定;随熟化时间增加,复合体系中[Al+Fe]a含量逐渐减少,[Al+Fe]b和[Al+Fe]c含量均增加,当熟化时间超过48 h之后,NFAC-PEM/AM絮凝剂中[Al+Fe]形态分布基本保持稳定。Ferron-complexation ti med spectrophotometry was used for [Al＋Fe] species analysis in NFAC-PEM/AMcomplex flocculant.The effects of reaction conditions on[Al＋Fe] species were examined.The results showed that with the decrease of m（NFAC）∶m（PEM/AM）,the content of [Al＋Fe]a remained steady,[Al＋Fe]b decreased gradually and [Al＋Fe]c increased.With the increase of pH,the content of[Al ＋Fe]adecreased signifcantly,both the contents of [Al＋Fe]band [Al＋Fe]cincreased gradually.With the increase of reaction temperature,the content of [Al＋Fe]areduced a little,[Al ＋Fe]bcontent remained unchanged and [Al ＋Fe]ccontent in-creased accordingly.With the increase of aging time,the content of [Al ＋Fe]a reduced gradually,both the contents of [ Al ＋Fe]band [Al＋Fe]cincreased.When the aging time exceeded 48 h,the [Al＋Fe] species in NFAC-PEM/AMcomplex flocculant were al most invariable.
