摘要 锰叶绿素的形成和伏安行为乔庆东(抚顺石油学院应用化学系,抚顺113001)叶绿素广泛存在于绿色植物中,在光合作用中发挥着重要的生理功能 ̄[1].锰离子是植物生长中必需的金属离子之一,与植物的光化学析氧反应有密切关系 ̄[2]。系统地研究叶绿素和金属叶绿... The formation and voltam metric behavior of manganese chlorophyll werestudied.The electrochemical red uction mechanism of Mn chlorophyll a (MnChla)in aqueous solutionwas investigated and discussed.During the electrored uction of MnChla ,the porphyrin ring was singlyreduced with 2 electrons and the Mn ̄(2+) ion remained its original state,The reduction rate constant k_m=0.36/s was gained.
