在相边界电位的极化电位范围内的不稳定窗口的存在下的实验证据已获得在循环伏安图中的存在下的阴离子表面活性剂的转移跨越1，2-二氯乙烷-水界面。癸基磺酸根和十二烷基硫酸根离子在半波电位附近出现不规则的电流尖峰和波动。混沌电流随着离子型表面活性剂浓度的增加而变得更加明显。这一趋势与基于最近提出的电化学不稳定性概念的理论预测非常一致。
Experimental evidence for the presence of the instability window in the polarized potential range of the phase-boundary potential has been obtained in cyclic voltammograms in the presence of the transfer of anionic surfactants across the 1,2-dichloroethane–water interface. Irregular current spikes and fluctuations appeared in the vicinity of the half-wave potential for the transfer of decyl sulfonate and dodecyl sulfate ions. Chaotic current became more pronounced with increasing the concentration of the ionic surfactant. This trend was in excellent agreement with the theoretical prediction based on the recently proposed concept of the electrochemical instability.
