摘要
研究了超声波对Pb(Ⅱ )、Cu(Ⅱ )同时电分析化学测定条件的影响 ,并对其作用机理进行了初探。利用超声波的空化作用加快了质量传递 ,提高了电极活性 ,在电极表面既产生机械效应又产生热效应 ,从而提高了Pb、Cu同时电化学测定的灵敏度。
The effects of ultrasound on the simultaneous electrochemical determination of Pb(Ⅱ) and Cu(Ⅱ) were investigated, and the interaction mechanism was discussed. The experiments showed that the determination sensitivity of Pb(Ⅱ) and Cu(Ⅱ) increased due to ultrasound cavitation,which could enhance mass transfer and electrode activity, and proudce the mechanical and thermal efficiency at the surface of electrodes.
