湖水水样中铅离子检测方法用探针集成的功能核酸修饰电极
摘要：
本发明公开了一种湖水水样中铅离子检测方法用探针集成的功能核酸修饰电极，所述检测方法是将探针集成的功能核酸修饰电极浸入加有待测铅离子的缓冲液20~30分钟，取出洗涤并在0.1M的NaClO4电解质溶液中进行DPV测定，根据在0.1～0.6V范围内扫描记录的DPV峰电流信号的变化率来计算样品中的铅离子浓度。本发明选择性好、灵敏、简便、快速。
摘要（英）：

The invention discloses a probe integrated functional nucleic acid modified electrode for a lake water sample lead ion detection method. According to the detection method, the probe integrated functional nucleic acid modified electrode is immersed into buffer solution for 20-30min, wherein to-be-tested lead ions are added to the buffer solution; the probe integrated functional nucleic acid modified electrode is taken out for washing; DPV determination is carried out on the probe integrated functional nucleic acid modified electrode in 0.1M of NaClO<4> electrolyte solution; and concentration ofthe lead ions in a sample is computed according to a change rate of DPV peak current signals scanned and recorded in a range of 0.1-0.6V. The probe integrated functional nucleic acid modified electrode is good in selectivity and is sensitive, simple, convenient and rapid.
