【摘要】：以對(duì)苯二胺和乙二醛反應(yīng)生成的一種希夫堿碳氮聚合物為基材,添加Ag NO3,使Ag+與該聚合物中N原子配位形成一種復(fù)合材料,此材料高溫碳化形成了一種新的含銀摻氮碳材料.X射線衍射(XRD)結(jié)果顯示了該復(fù)合材料中單質(zhì)納米銀的存在;透射電子顯微鏡(TEM)顯示有納米銀線的存在;傅立葉紅外波譜(FTIR)證實(shí)此碳材料中—NH2、C—C、C迨C及C迨N隨著溫度升高而降低,銀在800℃以上時(shí)被原位還原為銀單質(zhì);X射線光電子能譜(XPS)表明材料中存在氮和銀,銀和氮有一定相互作用.該碳材料應(yīng)用于飲用水,研究其對(duì)大腸桿菌(E.coil)的抑菌性能.發(fā)現(xiàn)希夫堿與Ag的物質(zhì)的量之比為1∶0.8,材料的炭化溫度為800℃時(shí),此材料可具有1.54-log以上的對(duì)數(shù)去除率.實(shí)際水樣的應(yīng)用抑菌測(cè)試也顯示出令人滿意的抑菌效果,而且抗銀流失性能滿足國(guó)家飲用水標(biāo)準(zhǔn)GB5749-2006.
[Abstract]:A kind of Schiff base carbonitrogen polymer, which was formed by the reaction of p-phenylenediamine with Glyoxal, was used as the base material and Ag no _ 3 was added to make Ag coordinate with N atom in the polymer to form a composite material. The results of X-ray diffraction (XRD) show the existence of nanocrystalline silver in the composites, and the existence of nanocrystalline silver wires by transmission electron microscopy (TEM). Fourier transform Infrared Spectroscopy (FTIR) confirmed that the contents of -NH _ 2N _ C _ (C) C _ (C) and C _ (C) / N decreased with the increase of temperature, and that silver was reduced to silver in situ at 800 鈩，
