【摘要】 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^-7mol/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。更多还原

【Abstract】 A chemically modified carbon paste electrode was prepared by incorporating appropriate quantities of 2,9-dichloro-1, 10-o-phenanthroline directly into the paste mixture. Trace silver (Ⅰ) can be preconcen-trated on the electrode. The method showed good linearly for 1 ×10-9-5×10-7 mol/L silver(Ⅰ) in nitric acid medium. The electrode was verified by the determination of silver(Ⅰ) in waste water.更多还原
