我们已有的工作表明,用伏安法可以直接测定土壤中还原性物质的总量,并能概略地区分其易氧化和难氧化的部分。从电化学方法应用的进展看,这无疑是一个进步,但该法还不能满足进一步区分各种还原性物质的需要。由于铁的形态转化是土壤
Our work has shown that the voltammetric method allows direct determination of the total amount of reducing material in the soil and can roughly distinguish between readily oxidizable and refractory components. This is undoubtedly an improvement from the application of electrochemical methods, but the law can not meet the need to further distinguish between various reducing substances. Since iron forms the transformation is soil
