邻苯二胺(ODB),邻氨基酚(OAP)在酸性水溶液中易电聚合,可形成致密的聚合膜。聚邻苯二胺(PODB)在PH<4时具有电活性,其氧化还原反应与电变色效应对应。聚邻苯二胺,聚邻氨基酚(POAP)膜电极电位在pH=4~10范围对pH有Nernst响应,电极系数分别为59mV/pH和57mV/pH。响应时间小于3分钟。PODB,POAP膜能与Ni~(2+),Co~(2+)过渡金属离子形成稳定的聚合络合膜。此膜在碱性介质中具有稳定的循环伏安行为,膜中的金属离子可被H~+交换。PODB电极的—NH_2基可再修饰引入醌/氢醌功能菌。
O-phenylenediamine (ODB), o-aminophenol (OAP) in acidic aqueous solution easy to electrically polymerize, can form a dense polymeric membrane. Poly-o-phenylenediamine (PODB) is electrically active at pH <4 and its redox reaction corresponds to the electrochromic effect. Poly (ortho) phenylenediamine (POAP) membrane electrode potentials show Nernst response to pH in the range of pH = 4 ~ 10, with electrode coefficients of 59mV / pH and 57mV / pH, respectively. Response time is less than 3 minutes. PODB, POAP film with Ni ~ (2 +), Co ~ (2+) transition metal ions to form a stable polymer complex membrane. This membrane has a stable cyclic voltammetric behavior in alkaline medium, and the metal ions in the membrane can be exchanged by H ~ +. The -NH_2 group of PODB electrodes can be modified to introduce quinone / hydroquinone functional bacteria.
