摘要

采用炭化木质素粉作为氯化银-氯化银参比电极的盐桥。这种易于制备的参比电极在饱和氯化钾溶液中表现出优异的稳定性。电化学阻抗谱表明，制备的参比电极在酸性、中性和碱性水溶液(pH 1 ~ 12)中均稳定，阻抗与等效玻璃熔块相似。

Lignin-based porous junction for silver-silver chloride reference electrodes

Carbonized lignin powder was used as a salt bridge for a silver-silver chloride reference electrode. This easy-to-prepare reference electrode exhibited excellent stability in saturated potassium chloride solution. In addition, the electrochemical impedance spectra showed that the prepared reference electrode is stable in acidic, neutral, and basic aqueous solutions (pH 1 - 12) and has similar impedances to its glass frit equivalent.
