The Polargraphic wave is characterized by an adsorptive reduction wave,and the Peak potential is about -0.52 V （vs.SCE）. The peak height is linear with inosine concentration over a range of 8×10-7 mol/L to 2×10-5 mol/L. The method has been developed for the determination of inosine in pharmaceutical. 肌苷 铜 络合物吸附波 inosine cupper ion polarographic wave R977.3 1994-01-01 2021-04-01 1
