阿霉素(ADM)在0.1mol/LHAc-NaAc底液(pH4.3),富集电位-0.20V(vs.Ag/AgCl)、富集时间120s、扫速100mV/s等条件下,于悬汞电极上产生一灵敏的吸附伏安还原峰,峰电位为-0.45V,峰电流与ADM浓度在1.0×10-9~4.0×10-7mol/L范围内呈线性关系,检测限可达5.0×10-10mol/L。该法用于病人尿样中ADM的测定,得到满意的结果。用多种电化学手段研究了阿霉素的伏安行为和反应机理,测定了有关参数。实验表明,体系属可逆吸附波。
Adriamycin (ADM) under the conditions of 0.1mol / L HAc-NaAc (pH4.3), enrichment potential -0.20V (vs.Ag/AgCl), enrichment time 120s and sweep speed 100mV / s , A sensitive adsorption voltammetric reduction peak was generated on the hanging mercury electrode with the peak potential of -0.45V and the peak current and ADM concentration in the range of 1.0 × 10-9 ~ 4.0 × 10-7mol / L Linear relationship, detection limit of up to 5.0 × 10-10mol / L. This method is used in the determination of ADM in patients with urine samples, with satisfactory results. The voltammetric behavior and reaction mechanism of doxorubicin were studied by a variety of electrochemical methods. The relevant parameters were determined. Experiments show that the system is reversible adsorption wave.
