摘要：

The binding of Hg(II) with humic acid, incorporated into the carbon paste electrode, was verified. This modified humic acid electrode was used for the trace determination of Hg(II). The differential-pulse voltammetry on the electrode modified with humic acid yielded good performance over the concentration range 5 X 10(-8) - 5 X 10(-7) M Hg(II). Only Cu(II) interferes with the determination.
