A simple pH probe is developed based upon the covalent chemical derivatisation of carbon particles with anthraquinone. The amperometric response of electrodes constructed from this material is examined and shown to produce a Nernstian linear response to pH from 1 to 9, over a range of temperatures from 20 to 70 degrees C, consistent with a two-electron, two-proton electrochemical process.
基于蒽醌对碳颗粒的共价化学衍生化开发了一种简单的pH探针。研究了用这种材料构建的电极的安培响应,结果表明,在20至70摄氏度的温度范围内,该电极对pH值在1至9之间产生能斯特线性响应,这与双电子、双质子电化学过程一致。
