| 摘要: |
| 采用稀土电极材料六硼化镧制备了一种新的全固态铁离子敏感电极。研究了该敏感电极在常见介质中对Fe3+的响应行为。结果表明,该铁离子敏感电极在1.5mol/LH3PO4介质中的线性响应范围、检测下限和响应斜率分别为1.0×10-5~1.0×10-1 mol/L Fe3+,6.0×10-6 mol/L Fe3+和60mV/pC,且具有较好的选择性。 |

| Abstract: |
| A new all Solid-state electrode for Fe(Ⅲ) ion has been fabricated with rare-earth material LaB6 prepared by us. The electrode response behaviour toward Fe(Ⅲ) in several medium was investigated. The results show that the linear tesponse range, detection limit and response slope of the Fe(Ⅲ) ion sensitive electrode in 1.5 mol/L H3PO4 medium are 10-5~-1 mol/L, 6×10-6 mol/L Fe3+ and 60 mV/pC rerspectively, and with good selectivity. |
