以林可霉素与硝酸汞配合比为1∶1的配位化合物作为电活性物质,研制了林可霉素-汞修饰树脂膜电极,并对影响其电化学性能的一些因素进行了探究,得到了良好的电极响应曲线,响应斜率为[(5)(8)].8mV/pC,线性范围达4个数量级,检出限为[(1.0)(327)(10)]-5mol/L,十多种常见无机离子与一些辅料对电极基本无干扰,可采用直接电位法测定市售注射液中的林可霉素主含量。 The electrochemically active substance, a complex of lincomycin and mercury nitrate, was used as the electroactive substance. The lincomycin - mercury modified resin membrane electrode was developed and some factors influencing its electrochemical performance were explored. A good electrode response curve was obtained with a response slope of [(5) (8)]. 8mV / pC with a linear range of 4 orders of magnitude with a detection limit of [(1.0) (327) / L, a dozen kinds of common inorganic ions and some excipients on the electrode basically no interference, direct potentiometry can be used to determine the main lincomycin levels in the commercially available injection.
