Abstract:The novel construction method for the detection of Pb(Ⅱ ) has been developed using synchronous plating bismuth film on the multi-walled carbon nanotube (MWCNT)-ionic liquid (BMIM]PFd modified electrode surface. The sensitive anodic stripping peak of Pb2+ was obtained at the proposed sensor. Under the optimum conditions, stripping peak current of Pb2+ has good linearity with concentration in the range of 3.0 × 10^-7 -2.0 × 10-5 tool/L, and the detection limit is 6.0 × 10^-8 mol/L. The resulting sensor is easy to prepare with good repeatability and can be used for determination of Pb( Ⅱ ) ion in blood samples.
Keywords:multi-walled carbon nanotube  ionic liquid  modified electrode  synchronous plating bismuth film  rb(Ⅱ)
