摘 要:本文用电位扫描法研究了锑在HCI溶液中的阳极溶解过程。根据Stern-Geary方程,用电子计算机求出锑的电化学溶解速度(用腐蚀电流表示)Icorr,Tafel常数bA,bC和极化电阻Rp。它们分别为Icorr=19.90mA/cm2,bA=39.80mV.bC=39.80mV和Rp=0.4342Ω·cm2,并对锑溶解过程的影响因素进行了讨论。
Abstract: The process of anodic dissolution of Sb in HCl solution has been studied bypotential scan method.With the computer,we have calculated the Tafel constantsbA and bc,the polarization resistance Rp,and the dissolution rate of Sb,which isrepresented by corrosion current Icorr.The results are as follows:bA=39.80mV,bc=39.80mV,Rp=0.4342Ω·cm2,and Icorr=19.90mA/cm2.What influences thedissolution of Sb has also been discussed.
