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.
