Significant Difference

Electrochemical sensors can detect the heavy metal ions in seawater quickly, conveniently and accurately with the advantages such as the fast detection speed, the simple operability and the low cost. The ionic liquid [Emim]CH3SO3 showed excellent electrochemical performance and could meet the initial application requirements as electrochemical sensors. The characters of the ionic liquids [Emim]CH3SO3 and [Emim]PF6 which include IR, LC-MS, conductivity, electrochemical window and viscosity were detected. The influ-ence of trace impurity on the conductivity of the ionic liquids was investigated. Results suggested that the conductivity of the ionic liquids increased with the concentration of the added organic solvents. In addition, though the conductivity of the ionic liquids increased with temperature, there is no significant difference in the influence of the same impurity at varying temperatures. Muti Walls Carbon Nanotubes (MWCNTs) are appropriate materials which are commonly used materials for electrochemical sensor applications. The effect of theImidaz-olium-based ionic liquids on the performance of the conductivity of the MWCNTs was studied. It was found that Ionic liquid is an excellent extraction agent for metal ions and its presence in the sensor system improves significantly the detection of heavy metal ions.

Ionic liquids are expected to replace conventional organic solvents in organic synthesis, solvent extraction and electrochemistry due to their unique characters such as low volatility, high stability and so on. In this work, N , N ,-diethyl- N -methyl- N -(2-methoxyethyl) ammonium bis(trifluoromethansulfonyl)imide was used as an alternative solvent to extract heavy metal ions. As the extracting conditions, the additional effect of 8-hydroxyquinoline (8-HQ) as metal chelating agent into ionic liquids, shaking time and volume ratio were investigated. As extraction efficiency depended on 8-HQ concentration significantly, in order to extract high concentrated metal ions the solubility of 8-HQ into ionic liquid was tested. N , N ,-diethyl- N -methyl- N -(2-methoxyethyl) ammonium bis(trifluoromethansulfonyl)imide had good solubility of 8-HQ. Consequently, 5 μmol of copper, zinc, cadmium and manganese could be completely recovered with 100 μl of ionic liquid.
