摘要：

以层间插入十二烷基磺酸钠的镁铝类水滑石（Mg/Al-SDS-HTLc），与十六烷基三甲基溴化铵（CTAB）和3-氨丙基三乙氧基硅烷（APS）缩合反应制备了氨基化镁铝类水滑石（Mg/Al-NH2-HTLc）。 然后以Mg/Al-NH2-HTLc修饰热解石墨电极，通过循环伏安法探讨了该电极对吸附在其表面的大肠杆菌的杀灭作用。 结果表明，被吸附的大肠杆菌在经过循环伏安扫描后死亡率达到98.68%，大肠杆菌的死亡可能是由于细胞膜中易氧化物质（如鸟嘌呤）被氧化所致。

Abstract:

Amino-hydrotalcite like compound(Mg/Al-NH2-HTLc) was prepared by Mg/Al-hydrotalcite like compounds by intercalating sodium dodecyl sulfate(Mg/Al-SDS-HTLc) followed by condensation reactions with hexadecyltrimethyl ammonium bromide(CTAB) and (3-aminopropyl)triethoxysilane(APS). Then, it was used to modify graphite electrode for the adsorption of Escherichia Coli(E.coli). Cyclic voltammetry(CV) was used to investigate the disinfection of the modified electrode. The result showed that the germicidal efficiency could reach to 98.68% and the possible disinfection mechanism might be the oxidation of the substance(such as guanine) within the membrane of E.coli.

Key words: Amino-Hydrotalcite Like, Modified Electrode, Escherichia Coli, Disinfection
