| Abstract: |
| The corrosion inhibition of benzalkonium on zinc in 3%hydrofiuoric acid solution was investigated with different temperatures and different concentration of benzalkonium by weight-loss method. The results show that the benzalkonium bromide on the corrosion of zinc has a good inhibitory effect in 3% hydrofluoric acid solution. The corrosion inhibition of benzalkonium bromide increases with the increaesing of concentrations of benzalkonium bromide.When its concentration reaches a certain concentration, corrosion inhibition remaines basically unchanged. According to the structural theory analysis the adsorption of benzalkonium on the surface of zinc is the important reason resulted from corrosion inhibition, benzalkonium bromide in the surface of zinc to obey the law of Langmuir adsorption isotherm. The experimental data are treated by the Sekine metheod and the correlative thermodynamics parameters are obtained. |
