摘要

本研究探讨了一种创新的、一次性的、经济的电化学平台的创建，用于抗生素头孢曲松的检测。采用还原氧化石墨烯和二硫化钼丝网印刷电极。采用差分脉冲伏安法测定，检出限为0.28 μmol L-1。该传感器被有效地用于评估曼谷三个不同池塘的地表水样品，在没有任何样品制备的情况下，相对回收率为92.2%至112.6%。尽管存在结构类似的抗生素，如环丙沙星、阿莫西林、氨苄西林、链霉素、庆大霉素和头孢氨苄，但该传感器对头孢曲松具有显著的选择性。所研制的电化学传感器对环境水样中头孢曲松的检测具有良好的灵敏度、选择性和实用性。

Green disposable rGO/MoS2 sensor for ceftriaxone detection in surface water

This study investigates the creation of an innovative, disposable, and economical electrochemical platform for the detection of the antibiotic ceftriaxone. A screen-printed electrode of reduced graphene oxide and molybdenum disulfide was used. Differential pulse voltammetry was employed for the measurements, resulting in a detection limit of 0.28 μmol L⁻¹. The sensor was effectively utilized to evaluate surface water samples obtained from three distinct ponds in Bangkok, attaining relative recovery rates ranging from 92.2 % to 112.6 % without any sample preparation. The sensor demonstrated remarkable selectivity for ceftriaxone, despite the presence of structurally analogous antibiotics such as ciprofloxacin, amoxicillin, ampicillin, streptomycin, gentamicin, and cefalexin. The developed electrochemical sensor exhibited good sensitivity, selectivity, and practical applicability for the detection of ceftriaxone in environmental water samples.
