摘　　要：筛选了一系列过渡金属催化剂,发现氯化钯对氯霉素表现出优异的电催化还原性能,检测限低至0.02μM,即6 462.8 pg/mL,线性范围0.02~20μM。除此之外,氯化钯催化剂还具有良好的电化学稳定性和特异性,经过十圈差分脉冲伏安扫描后峰电流基本不变,并且能排除三种具有同类结构(苯环)或官能团(硝基)化合物的干扰。因此,氯化钯是一种在电化学检测氯霉素中具有发展潜力的催化剂。This work selected a serial of transitions metal catalysts and found that palladium chloride exhibits excellent electrocatalytic reduction performance on chloramphenicol. The limit of detection can reach 0.02 μM(6 462.8 pg/mL) with a linear range of 0.02~20 μM. Besides, palladium chloride displays well electrochemical stability and anti-interference capability. After ten cycle differential pulse voltammetry measurement, the peak current almost remain as the initial one. And it also shows good selectivity of chloramphenicol in the existence of three interfering species with similar structures(benzene ring) or groups(nitro group). Therefore, palladium chloride is a potential catalyst in electrochemical determination on chloramphenicol.
