合成了2,9-二氯-1,10-邻菲啰啉,并以此化合物研制了对银有灵敏响应的碳糊电极。在硝酸介质中,银离子浓度在1×10~(-9)～5×10~(-7)mol/L范围内与阳极溶出峰电流呈良好的线性关系,线性相关系数0.996。电极用于电镀废水中银的测定,结果令人满意。
Synthesis of 2,9-dichloro-1,10-phenanthroline, and the compound developed a sensitive silver carbon paste electrode. In nitric acid medium, the concentration of silver ions in the range of 1 × 10 -9 -9 × 10 -7 mol / L showed a good linear relationship with the anodic dissolution peak current with a linear correlation coefficient of 0.996. Electrode for the determination of silver in electroplating wastewater, the results are satisfactory.
