首发时间:2010-05-26
摘要:提出EDTA/ATT复合物修饰玻碳电极测微量Hg2+的新方法。本文利用酸化凹凸棒土(ATT)与乙二胺四乙酸-4Na(EDTA)制备了EDTA/ ATT复合物,并将该复合物固定在玻碳电极表面上,运用循环伏安法研究Hg2+在薄膜修饰电极上的电化学行为,并据此测量溶液中痕量Hg2+。

Electrochemical behavior of Hg2+ in EDTA/ATT modified electrodes
Abstract:Forward new methods to test Hg2 +,which is EDTA/ ATT modified glassy carbon electrode. This paper using acidizing attapulgite (ATT) and ethylenediamine tetraacetate - 4Na (EDTA) preparation for complex, then fix it on the surface of glassy carbon electrode, research electrode electrochemical behavior of Hg2 + by cyclic voltammetry, and measuring the concentration in the solution.
Keywords: electrochemical attapulgite EDTA electrode Hg (Ⅱ)
