用水合肼在碱性条件下还原NiSO4的方法合成了镍纳米粒子，进而将其表面功能化，合成了磁性NiHCF纳米粒子，用其制备了磁性NiHCF纳米粒子修饰石墨电极。在PH=7.4的PBS缓冲溶液中，磁性NiHCF纳米粒子修饰电极对水合肼有显著的催化氧化作用，水合肼氧化峰的峰电流与浓度在6.36×10-7~1.29×10-4mol/L范围内呈良好的线性关系（r=0.9987），检出限为 2.12 ×10-8。论文利用电化学工作站研究了不同反应液PH、不同摩尔比、不同反应时间条件下对合成PB磁性颗粒的影响；对合成的PB磁性粒子进行了TEM及红外吸收光谱表征；研究了磁性NiHCF纳米粒子修饰电极对水合肼的电化学响应以及该修饰电极的重现性和稳定性。磁性NiHCF纳米粒子修饰石墨电极具有制作简单、价格低廉、灵敏度高、选择性好、电极表面易更新、稳定性和重现性好等优点。该电极已成功用于水样中肼的测定. 一定要准确翻译哈。谢谢！ |

| With hydrazine hydrate in alkaline NiSO4 way to restore the synthesis of nickel nanoparticles, which function of its surface, NiHCF synthesized magnetic nanoparticles were prepared using the NiHCF magnetic nanoparticles modified graphite electrode. PH = 7.4 in the PBS buffer solution, the magnetic nano-particles modified electrode NiHCF of hydrazine hydrate significant role in catalytic oxidation, hydrazine hydrate oxidation peak current and concentration of 6.36 × 10-7 ~ 1.29 × 10-4mol / L range showed a good linear relationship (r = 0.9987), the detection limit of 2.12 × 10-8. Electrochemical workstation paper studied the use of different reaction solution PH, different molar ratio, different reaction time under the conditions of magnetic particles on the synthesis of the impact of PB; the PB on the synthesis of magnetic particles and the TEM characterization of infrared absorption spectrometry; study of magnetic nano-NiHCF particles modified electrode electrochemical hydrazine hydrate as well as the modified electrode response reproducibility and stability. NiHCF magnetic nanoparticles modified with a graphite electrode producing simple, low cost, high sensitivity and selectivity, the electrode surface easy to update, stability and the advantages of good reproducibility. The electrode has been successfully used for water samples in the determination of hydrazine. |
