运用电化学测量、ICP-AES分析和SEM形貌观测技术研究铪在Et4NBr为支持电解质的无水异丙醇与乙腈(ACN)溶液中的电化学腐蚀行为。结果表明,开路电位随着浸入时间的增加而不断变正,直到达到一个较稳定数值,开路电位的上升与表面氧化膜钝化有关。在线性极化曲线中接近腐蚀电位的阳极极化段未出现活性溶解,这是其表面自发形成...
乙腈-水系统 1. The sample was separated on Atlantic C18 column,detected at 211nm,acetonitrile-water system as flow phase,the results showed the gradient A was the optimal detection gradient,in this condition three higher alcohols could be separated Absolutely and quickly. 结果表明:以乙腈-水系统...
