氯化血红素(Ha)能较稳定地吸附在热解石墨电极表面上,该电极在0.5MH_2SO_4水溶液中循环伏安法研究表明,在100mV(vs.SCE)和-170mV(vs.SCE)附近有两对峰,分别指认为Ha的单体(monomer)吸附态和二聚体(dimer)吸附态。
The hemin can be more stably adsorbed on the surface of pyrolytic graphite electrode. The cyclic voltammetry of the electrode in 0.5MH 2 SO 4 aqueous solution shows that at about 100mV (vs.SCE) and -170mV (vs.SCE) There are two pairs of peaks, which are respectively designated as monomer adsorption states and dimer adsorption states of Ha.
