摘要
炭糊电位广泛应用于伏安法的测定,特别是修饰的炭糊电极,对于提高灵敏度和选择性具有极大的潜力,我们首次应用炭糊电极作为银离子的电位传感器,发现其具有制作方便、灵敏度高以及采用适当的掩蔽措施可得到较好的选择性等优点。 1 实验部分 1.1 仪器和试剂 pHS-10A数字酸度/离子计(萧山市科学仪器厂),pHS-2型酸度计(上海第二分析仪器厂).314 S^(2-)离子选择电极(江苏电分析仪器厂)。
The carbon paste electrode was used as the trace silver potential sensor. This electrode system exhibits a linear response over the range of 5× 10-7-1×10-2 mol/L for trace of silver, and according to 1UPAC recommendation, the detection limit of this electrode system is 1 × 10-7 mol/L. The electrode has been used to determine trace of silver in electroplate solution and fix solution with good results.
