Differential semi-differential cyclic voltammetry (DSCV) for the electrolysis at the oil/water interface has been studied. In the system of 0.01 mol/L LiCl(w)-0.01 mol/L TBATCIPB(nb), the 'potential window' extended about 50 mV in positive direction as compared with the base electrolyte of TBATPB(nb). The residual current was almost eliminated so that both sides of the platform in the 'potential window' enlarged about 50 mV respectively. The interface capacity calculated was about 16μF/cm~2. The transfer of succinylcholine ion across the w/nb interface has been investigated by using DSCV. The characteristics of DSCV wave were similar to those of semi-differential cyclic voltammogram, but the peak shape was improved and the detection limit was decreased about 1 order (1.0×10~(-6)mol/L). The linear range was 1.0×10~(-6)～1.2×10~(-4)mol/L and the relative standard deviation was within 5%. It can be used for the determination of succinylcholine ion.
