Voltammetry Voltammetry comprises microelectrolysis techniques in which the working electrode potential is forced by external instrumentation to follow a known potential-time function and the resultant current- potential and current-time curves are recorded and analyzed to obtain information a bout the solution composition. Depending on the shape of the potential-time perturbing (ta)signal and on the mode of the analyte transport, voltammetric techniques can be subdivided as Linear potential sweep volatmmetry(线性电位扫描伏安法) Potential step method(电位阶跃法) Hydrodynamic methods(流体动力学方法) Stripping voltammetry(溶出伏安法)Voltammetry comprises microelectrolysis techniques in which the working electrode potential is forced by external instrumentation to follow a known potential-time function and the resultant current￾potential and current-time curves are recorded and analyzed to obtain information about the solution composition. Depending on the shape of the potential-time perturbing (扰动)signal and on the mode of the analyte transport, voltammetric techniques can be subdivided as : Linear potential sweep volatmmetry （线性电位扫描伏安法） Potential step method （电位阶跃法） Hydrodynamic methods （流体动力学方法） Stripping voltammetry （溶出伏安法） Voltammetry
