Effects of Nascent particiulate on the Rate of Mn (22222) Oxidation near the Seawater sediment Interface

Hong Jiazhen Li Lian Tang Guping Li Faxi (Department of Oceanography)  
Effects of hydrous Fe (Ⅲ) oxide particulate that absorbs silicate and heavy matals like Cu, Pb, Co、Ni and the FeS Precipitate on the rate of Mn(Ⅱ)oxidation have been studied under simulated conditions adjacent to seawater sediment interface. A first order relationship between the rate of Mn(Ⅱ) oxidation and Mn(Ⅱ) concentration was observed, when nascent hydrous Fe(Ⅲ) oxide or FeS were present in mili molar levels within the system. The rate constant of Mn(Ⅱ) oxidation decreases when the Fe(Ⅲ) oxide absorbs more silicte, but it is unchanged when Fe(Ⅲ) oxide absorbs the heavy metals. The numerical values of the rate constant for Mn(Ⅱ) oxidation are comparable in the same magnitude in the cases of Fe(Ⅲ) oxide and FeS.
【Key Words】： Nascent paniculate Mn(Ⅱ) oxidation rate Seawater sediment interface
