Studies on corrosion inhibition property and antimicrobial ability of quaternary polyethyleneimine

Zhang Xin Gao BaoJiao Shen YanLing (Department of Chemical Engineering North University of China Taiyuan 030051)  
Quaternary Polyethyleneimine(QPEI) was prepared and the corrosion inhibition property of QPEI for low carbon steel which was dipped in aqueous solution of H2SO4 of 0.5mol/L were mainly investigated by using weight-loss method,and the antimicrobial ability of this polymeric quaternary ammonium salt was researched with the method of plate counting live bacterium by using Escherichia Coli as a disease-leading bacterium.The antimicrobial mechanism of QPEI was studied more deeply via measuring the activities of TTC-dehydrogenase.The experiment results show that QPEI possesses excellent corrosion inhibition property and very strong antimicrobial ability.The results of measuring activities of TTC-dehydrogenase show that the antimicrobial mechanism of QPEI is based on a sterilizing bacterium process,and not only is based on a restraining action.
