为了获得饮用水的安全性，将银（Ag）负载到纤维状亚氨基二乙酸酯（IDA）吸附剂上制备了抗菌材料，该吸附剂通过甲基丙烯酸缩水甘油酯的辐射诱导接枝聚合，然后将生成的环氧基团化学修饰为IDA基团（IDA-Ag）而合成。 IDA-Ag织物上负载的Ag总量为0.4mmol-Ag/g-织物。通过扫描电子显微镜能量色散X射线光谱仪观察IDA-Ag织物横截面，Ag均匀地分布在IDA层中。通过使用溪流的柱式水流试验来评价抗菌效果，结果发现，无论流速如何，有效Ag浓度均为0.05ppm，这对抗菌性能起作用。对于一般细菌，直到BV（BV：蒸汽水体积/IDA-Ag织物体积）6000为止显示抗菌效果，对于结肠炎病菌军团直到BV 6000为止完全消毒。
To obtain the safety of drinking water, an antibacterial material was prepared by loading silver (Ag) onto fibrous iminodiacetate (IDA) adsorbent, which was synthesized by radiation-induced graft polymerization of glycidyl methacrylate and subsequent chemical modification of the produced epoxy group to an IDA group (IDA-Ag). A total amount of loaded Ag on the IDA-Ag fabric was 0.4 mmol-Ag/g-fabric. From an observation of the IDA-Ag fabric cross section by a scanning electron microscope energy dispersive X-ray spectrometer, Ag was distributed to IDA layer uniformly. As a result of evaluating antibacterial effects by the column mode water flow test with stream water, the effective Ag concentration was monitored 0.05 ppm at irrespective flow rate which was functioned to the antibacterial performance. The antibacterial effects for general bacteria were indicated until BV (BV: steam water volume/IDA-Ag fabric volume) 6000, and for colitis germ legions were completely disinfected until BV 6000.
