摘　　要：针对传统Miner法的缺陷,本文采用模糊Miner法对复合树脂合成的过程中存在的模糊现象进行数学拟合图形分析,对最佳合成方法进行定量的描述。采用共沉淀法将水合氧化铁固载于大孔弱碱性阴离子树脂D301上,制备得到载铁复合树脂。采用扫描电镜、红外光谱、原子吸收、比表面积分析仪等并对其结构和性质进行表征分析,获得载铁树脂前后的表面形貌和化学结构的变化。稳定性实验结果表明,制备过程中通过负载时间为72h时,最大载铁量为31mg/g;经过去离子水稳定性实验发现,负载的水合氧化铁含量保持稳定。In view of the defects of the traditional Miner method,the fuzzy Miner method is used to analyze the fuzzy phenomena in the process of composite resin synthesis,and the best synthesis method is described quantitatively.Hydrated ferric oxide was impregnated on the macroporous weakly anion exchange resin D301 by chemical precipitation method,iron-impregnated composite resin was prepared.The structures and properties were characterized using scanning electron microscopy,Fourier transform infrared spectroscopy,atomic absorption spectro-photometer and specific surface area analyzer,the changes of surface morphology and chemical structure before and after iron-impregnated composite resin were examined.The stabilization test indicated that impregnation time was 72 h,the maximum iron content was wajup to 31mg/g;through the experiment testing stabilization in the deionized water,impregnated ferric oxide was found very stable.
