采用开路电位法、循环伏安法、动电位极化法和电化学阻抗法研究了三乙烯四胺（TETA）对硫酸介质中黄铁矿氧化的抑制作用。实验结果表明，TETA是一种有效的抑制黄铁矿氧化的包覆剂，其抑制效果随TETA含量的增加而增强。动电位极化曲线表明，TETA浓度从1%增加到5%时，缓蚀效率（η%）从42.08%增加到80.98%。这些结果与EIS的测量（43.09%至82.55%）一致。动电位极化曲线也表明TETA是一种混合型缓蚀剂。
The potential of triethylenetetramine (TETA) to inhibit the oxidation of pyrite in H2SO4 solution had been investigated by using the open-circuit potential (OCP), cyclic voltammetry (CV), potentiodynamic polarization, and electrochemical impedance (EIS), respectively. Experimental results indicate that TETA is an efficient coating agent in preventing the oxidation of pyrite and that the inhibition efficiency is more pronounced with the increase of TETA. The data from potentiodynamic polarization show that the inhibition efficiency (η%) increases from 42.08% to 80.98% with the concentration of TETA increasing from 1% to 5%. These results are consistent with the measurement of EIS (43.09% to 82.55%). The information obtained from potentiodynamic polarization also displays that the TETA is a kind of mixed type inhibitor.
