早在40多年前有报道曾指出,在海洋沉积物有机质与铁的相互作用中,铁与有机碳浓度变化的一致性。但由于铁和有机碳通常都吸附于黏土矿物表面,这种相互作用被简单地描述为:表面面积大、吸附能力强的细粒物质表面,铁和有机质含量会相应增加。但尚不明确的是,这种关联是源于他们对固体表面强大的亲和力,还是反映了铁对有机碳的保存的促进作用?铁有利于有机质的保存,在实验研究中得到了验证。同时,研
As early as more than 40 years ago, it has been reported that the consistency of iron and organic carbon concentrations in the interaction of organic matters and iron in marine sediments has been pointed out. However, since iron and organic carbon are usually adsorbed on the surface of clay minerals, this interaction is simply described as: the surface area of large, strong adsorption capacity of the surface of fine particles, iron and organic matter content will be increased accordingly. However, it is not yet clear whether this association stems from their strong affinity for solid surfaces or whether iron contributes to the preservation of organic carbon. Iron is beneficial to the preservation of organic matter and has been validated in experimental studies. At the same time, research
