package. The molecular graphics were plotted using SHELXTL. Atomic
scattering factors and anomalous dispersion corrections were ta-
ken from International Tables for X-ray Crystallography [22].
Cd-IL/CPE has been performed, and further investigation on the
mediation of biomacromolecules is under way.

3.3. Preparation of Cd-IL/CPE
This work was supported by the Natural Science Foundation of
Shandong Province (No. Z2007B01), PR China.
The traditional CPE was prepared by hand-mixing of graphite
powder with paraffin at a ratio of 70:30 (w/w) in an agate mortar.
The homogeneous carbon paste was packed into a cavity of a glass
tube with an inner diameter of 3 mm. The electrical contact was
provided by a copper stick. The Cd-IL/CPE was prepared according
to the following procedure: 0.4 g of Graphite powder and 0.1 g of
Cd-IL were mixed thoroughly in a mortar and heated at 100 °C to
form a homogeneous carbon paste. A portion of the carbon paste
was filled into one end of a glass tube (inner diameter 3 mm)
and a copper stick was inserted through the opposite end to estab-
lish an electrical contact. The Cd-IL/CPE surface was smoothed on a
piece of weighing paper just before use.

The amount of a modifier (Cd-IL) in the paste was optimized.
We investigated the graphite powder and Cd-IL at the ratios of
6:1, 5:1, 4:1, and 3:1 (w/w), and found that the optimal prepara-
tion condition was 4:1. When the amount of the Cd-IL was too lit-
tle, the bonding degree of graphite was bad, easy to fall off and
smash. Conversely, the amount of the Cd-IL was too large, the mix-
ture was so hard that it was difficult to shape it.

In summary, a new metal-containing ionic liquid of [(C10H21)2-
bim]2[Cd2Cl6] was synthesized and the structure was character-
ized. The electrochemical behavior and electrocatalysis of the Cd-
IL/CPE had been investigated. The Cd(II)-containing ionic liquid
had double function of a binder and an electrocatalyst. This modi-
fied electrode showed excellent electrocatalytic activities toward
the reduction of the hydrogen peroxide and bromate, and the re-
sults were reproducible with a lower detection limit, which was
suitable for the quantitative analysis of environmentally hazardous
materials. The advantages of the Cd-IL/CPE are its stability, excel-
lent catalytic activity, low detection limit and simplicity of prepa-
ration in comparison with the other methods, which is important
for practical application on electrochemical sensors. In this work,
only the electrocatalytic activity of some small molecules at the
