头孢曲松(Ceftriaxone,CTRX)为第三代头孢菌素,具广谱抗菌活性,半减期很长,常用于手术前后的预防治疗感染。本文报道将样品经XAD-2树脂分离洗脱后,以差示脉冲吸附溶出伏安法测定了血液中CTRX。仪器与试剂 PAR 174A型极谱仪,303A型静滴汞电极。Ag-AgC1电极为参比电极,铂丝为辅助电极,富集电位-0.65 V,富集时间1分钟,扫描速度每秒5 mV,脉冲振
Ceftriaxone (Ceftriaxone, CTRX) is the third generation cephalosporin, with broad-spectrum antibacterial activity, long half-period, commonly used in the prevention and treatment of infection before and after surgery. This article reports the sample after XAD-2 resin separation and elution, differential pulse stripping voltammetry determination of the blood CTRX. Instruments and Reagents PAR 174A Polarography, 303A Electrostatic Drop Mercury Electrode. Ag-AgC1 electrode as the reference electrode, platinum wire as the auxiliary electrode, the enrichment potential of -0.65 V, enrichment time of 1 minute, the scanning speed of 5 mV per second, pulse vibration
