在０．ｌｍｏｌ／ＬＣｄＣｌ２一０．００５ｍｏｌ／Ｌ四苯砷四苯硼体系中，用半微分循环伏安扫描，显示了良好的乙酰螺旋霉素络合推动Ｃｄ２＋离子在界面传递的伏安波。其特性与常规半微分极谱波类似。△ψ随乙酰螺旋霉素的浓度增加向阴极方向移动。ｅｐ乙酰螺旋霉素的浓度呈线性相关，线性范围为２９～４３７Ｕ／ｍ１，检测限为７Ｕ／ｍｌ。重现性的相对标准偏差为３％左右，回收率为９７～１０２％。与生物法相比，测定样品结果的相对误差在±１％以内。
At 0. lmol / LCdCl2-0.005mol / L tetraphenyl arsenic tetraphenyl boron system, semi-differential cyclic voltammetry scan showed good acetyl spiramycin complex promote Cd2 + ions in the interface of the voltammogram. Its characteristics and conventional semi-differential polarographic wave similar. △ ψ moves toward the cathode with an increase in the concentration of acetylspiramycin. The concentration of acetylspiramycin was linearly correlated with the linear range of 29 ~ 437U / ml and the detection limit of 7U / ml. The relative standard deviation of reproducibility was about 3%, and the recovery rate was 97 ~ 102%. Compared with the biological method, the relative error of the measured sample results is within ± 1%.
