Three kinds of stainless steel (00Cr17Ni14Mo3(316L),0Cr18Ni9Ti(322),1Cr18Ni9(302) )and red copper of corrosion resistance to HCl were researched ,and samples was analyzed by sweep electron microscope (SEM)and energy dispersion spectrumer (EDS) .
The behaviors of aniline electropolymerization on DT 3, 40 Cr, copper, 420, 304, 321 and 316 L stainless steel had been studied in 0.1 mol/L H2SO4+0.1 mol/L C6H5NH2 solution using electrochemical measurements. The corrosion behaviors of those materials in 0.mol/L H2SO4 solution were also investigated by potentiodynamic method.
The copper complexes of the above ligands were used in catalytic asymmetrical Henry reactions.
Comparison of antibacterial ability of copper and stainless steel
In this paper, the electro-analysis and spectrophotometric analysis methods were used to study the antibacterial ability of copper and stainless steel materials.
coli) and photo-bacteria were used as samples, the antibacterial effect of stainless steel was very weak, while the percentage of bacteria dying from exposure to metallic copper for 30 min was over 90%.
The antibacterial ability of copper has a potential application in the field of disinfection, food packaging and piping of drinking water.
