【Abstract】 Microcalorimtry was used to study antibacterial activities of four kinds of Schiff base and its complexes and two kinds of metal ion compound on E.coli. According to the power time curves, the multiplication rate constant k , the genaration time t g ,antibacterial ratio I and heat q have been calculated from these thermograms. the experimental results show that different kind of compounds has different effect on E.coli, it follows the sequence of Zn SG>SG>Co(Ⅲ) SG>Cu(Ⅱ) SG in 50 mg·L -1 and sequence of Co(Ⅲ) SG～SG>Zn SG>Cu(Ⅱ) SG in 100 mg·L -1 , under the cation of different compounds, their metabolism thermograms are different, the mechanism of their action also different.更多还原
