摘要

To simulate the corrosion of galvanized steel, artificial zinc rust of zinc hydroxysulfate (Zn₄(SO₄)(OH)₆路nH₂O:ZHS路nH₂O) was prepared in the presence of Fe(II) and Fe(III) at 85 掳C. Adding Fe(II) and Fe(III) suppressed the crystallization, particle growth and adsorption of corrosive gasses such as CO₂ and SO₂ on ZHS路nH₂O. The effect of Fe(III) was much higher than that of Fe(II). On increasing Fe(III) added, the crystal structure turned following as ZHS路nH₂O 鈫?#xA0;a mixture of ZHS路nH₂O and 伪-FeOOH 鈫?#xA0;伪-FeOOH and altered the particle morphology from hexagonal plate to needle-like nanoparticles.
