In the present work, a novel sensitive electrochemical carbon paste electrode chemically modified with yttrium doped manganese oxide Mn 2 O 3 /Y 2 O 3 nanostructures was assigned for determination of marbofloxacin (MRB) using square wave voltammetry (SWV) method. MRB has a broad spectrum of bactericidal activity for the treatment of urinary, respiratory and dermatological diseases in bovines and their retention in animal meats and milk leads to adverse side effects for the consumer. Thus a rapid estimation of minor concentrations of MRB has exerted a great concern to ensure food safety. XRD, EDX, Raman spectroscopy, SEM, and TEM techniques were employed to characterize the samples. The electrochemical oxidation behavior of MRB shows irreversible anodic peak at 1.10 V vs Ag/AgCl, in Britton–Robinson buffer (BR) at pH 5.0. The relationship was rectilinear over the range 10 × 10 −9 –1.0 × 10 −4 M between the peak current and i...

钇掺杂氧化锰（Mn 2 O 3 / Y 2 O 3）修饰的高灵敏纳米绿碳糊电极的电化学测定牛氟沙星及其残留的制备。

在本工作中，指定了一种新型的用钇掺杂的锰氧化物Mn 2 O 3 / Y 2 O 3纳米结构化学修饰的敏感电化学碳糊电极，用于使用方波伏安法（SWV）测定马波沙星（MRB）。MRB具有广泛的杀菌活性，可用于治疗牛的泌尿，呼吸系统和皮肤病，并且它们保留在动物肉和牛奶中会给消费者带来不利的副作用。因此，快速估算微量MRB的浓度已引起人们极大的关注，以确保食品安全。XRD，EDX，拉曼光谱，SEM和TEM技术被用来表征样品。在pH 5.0的Britton-Robinson缓冲液（BR）中，MRB的电化学氧化行为在相对于Ag / AgCl的1.10 V下显示不可逆的阳极峰。
