| 摘 要： | 目的研制含氟毒物的检测芯片,实现氟乙酰胺等含氟毒物的快速电化学检测。方法利用氟离子选择电极制备含氟毒物的检测芯片,对芯片各项性能进行测试;建立氟乙酰胺染毒动物模型,使用制备的氟离子芯片检测染毒致死大白兔体内氟离子浓度。结果血液添加标准检测氟离子其线性响应范围为1～10-6mol/L,相关系数为0.9994,平均斜率接近理论斜率,检测限为5×10-7mol/L。染毒组大耳白兔血中氟离子含量较对照组高5～6倍（P〈0.01）,肝、肾、脑组织中氟离子含量较对照组高2～4倍（P〈0.01）。结论此含氟毒物的检测芯片检测氟离子快速、简便、灵敏,可应用于氟乙酰胺等含氟毒物中毒案件的初筛。 |

| Abstract: | Objective To develop a determination chip with fluorine-containing poison in order to implement quickly electrochemical detection of the samples with fluoroacetamide and other fluorine-containing poison in the practical case. Methods The determination chip with fluorine-containing poison was prepared by using fluoride ion selective electrode and the performances of the chip were tested. The model of poisoned rabbit by fluoroacetamide was established,and then the concentration of fluoride ion in the sample w... |
