Abstract
The invention discloses a gold electrode modified by an ionic liquid-silica solution-perfluorinated sulfonic ester cation exchanger. The gold electrode modified by the ionic liquid-silica solution-perfluorinated sulfonic ester cation exchanger is prepared by the steps of polishing and activating a gold electrode, repeatedly scanning the gold electrode under the voltage of -0.2 V to +1.4 V till a stable CV curve is obtained, oscillating and mixing a silica solution, 1% perfluorinated sulfonic ester cation exchanger and an ion liquid to obtain a compound solution, adding a proper amount of terpyridyl ruthenium solution, immersing the treated gold electrode into the terpyridyl ruthenium solution, taking out the treated gold electrode, and naturally airing at room temperature to obtain the product. The invention further provides a preparation method of the gold electrode modified by the ionic liquid-silica solution-perfluorinated sulfonic ester cation exchanger. The ion liquid has the characteristics of high electric conductivity, a wide electrochemical window and better chemical and electrochemical compatibility; the problem of film embrittlement in a sol-gel preparation process is overcome, and the sensitivity and the stability of an electrode are improved.
Description
Technical field
The present invention relates to the gold electrode that ionic liquid-silicasol-perfluorinated sulfonic acid ester cationite is modified.
Background technology
At present, the main method measuring lavo-ofloxacin has electrochemical process, Flow Injection Chemiluminescence, high performance liquid chromatography, spectrophotometric method, capillary electrophoresis, fluorimetry etc.But these methods, because of reasons such as sensitivity are not high, instrument is valuable, fail to be widely used.Electrochemiluminescence (Electrochemiluminescence, ECL) analytic approach have wide, the highly sensitive and instrument of the range of linearity simple, be convenient to the advantages such as detection.In recent years, the existing research of ElectrochemiluminescDetermination Determination LVLX, but prepare laminated film using the mutual supplement with each other's advantages of ionic liquid (Ionic liquid), silicasol (Silica sol) and Nafion three and fix bipyridyl ruthenium as decorative material and have not been reported.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides the gold electrode that ionic liquid-silicasol-perfluorinated sulfonic acid ester cationite is modified.
To achieve these goals, technical scheme provided by the invention is: the gold electrode that ionic liquid-silicasol-perfluorinated sulfonic acid ester cationite is modified, the preparation method of described gold electrode is: after being ground on emery paper by gold electrode, deerskin towel is thrown to minute surface with Al2O3, after washing away electrode surface burnishing powder, uses ultrasonic about 3 min of water, 1:1 ethanol, water respectively.Then be placed in 0.10 mol/L H2SO4 solution and carry out cyclic voltammetry activation, in-0.2 ~+1.4 V, be repeatedly scanned up to and obtain stable CV curve; Silicasol, 1% perfluorinated sulfonic acid ester cationite, ionic liquid vibration are mixed to get complex solution; The bipyridyl ruthenium solution adding 6.0 × 10-3 mol/L concentration in complex solution is appropriate, ultrasonic mixing, then the gold electrode handled well is immersed in above-mentioned solution, take out after 5 min under being placed in room temperature and naturally dry, obtain the gold electrode that ionic liquid-silicasol-perfluorinated sulfonic acid ester cationite is modified.
Beneficial effect of the present invention is: the gold electrode that ionic liquid-silicasol provided by the invention-perfluorinated sulfonic acid ester cationite is modified, ionic liquid has high conductance, wide electrochemical window, the preferably feature such as chemistry and galvanochemistry compatibility, not only overcome the embrittlement problem of film in collosol and gel preparation process, and improve sensitivity and the stability of electrode.
