【摘要】 选用8-羟基喹啉为配合剂，经柱前衍生后高效波相色谱法分离测定，建立了人发和血清中微量元素锌、钴、铜的含量测定方法，该法配合产物稳定性好，标准曲线的线性范围锌、铜均为0．8～4．0mg／L，钴为0．1～2．0mg／L，相关系数均0．999以上，批内、批间相对标准偏差均小于5％，加样回收率锌为（100．3±0.47）％，钴为（98．9±2．07）％，铜为（100.9±0．65）％。更多还原

【Abstract】 A HPLC method for the determination of Zn, Co, Cu in hair and serum was described. A precolumn derivation with 8-hydroquinoline as a complexing agent was used. The metal complex was stable.The linear range was 0.8~4.0 mg/L for Zn, Cu, and 0.1~2.0 mg/L for Co, the correlation coefficients all were greater than 0.999. RSD of inter-batch and intra-batch was within 5%. Spiked recoveries were (100.3±0.47)%, (98.9±2.07)% and (100.9±0.65)% for Zn, De and Cu, respectively.更多还原
