实验发现：储氢合金电极的活化性能随碱液浓度增大、温度升高以及浸泡时间的延长得到改善，主要由于KOH的强腐蚀性使合金表面由富Zr层转化为富Ni层，为氢的吸附离解起到催化作用，总结出最佳KOH处理液的实验参数：6mol/L、80℃、浸泡 2 4h ，在此条件下合金电极循环两周即达最大放电容量。

Experimental results indicated that the contaminants generally existed in mussel, such as α-HCH,β-HCH,γ-HCH,δ-HCH, o·p-DDT, p·p-DDT, p·p-DDD, were degraded completely under the above conditions, whereas DDE, aldrin and dieldrin were partly degraded. No detectable degradation of PCB 1242 and PCB 1248 were observed. Thus the conventional preparation of the contaminants using the columns packed with Florisil or SiO〓 could be left out.
