水溶性有机质对茶园土壤氟形态的影响OA北大核心CSCDCSTPCD
Influences of dissolved organic matter on fluoride fractions in soils
采用元素分析与傅里叶变换红外光谱相结合的方法分析了腐熟鸡粪中水溶性有机质(dissolved organic matter,DOM)的结构及组成,通过溶液连续提取-电位分析法分析茶园土壤中氟的形态及含量.结果表明,腐熟鸡粪DOM中C、O、H和N元素含量占元素总量的93％,其中C和O的含量大于H和N,C/H和C/N较大,C、H饱和度低,含有较多羧基、醛基、酮基等不饱和度高的物质.水溶态和有效态氟含量随外源DOM添加量的增加而降低,呈负相关关系；而土…查看全部>>
The structure and composition of dissolved organic matter (DOM) extracted from the composted chicken manure were analyzed using elemental composition analysis and Fourier transform infrared spectroscopy (FT1R) methods, and the impacts of this DOM on the fractions of fluoride in soil were analyzed by using sequential extraction procedure and potentiometric analysis methods. The contents of carbon and oxygen were higher than that of hydrogen and nitrogen, acco…查看全部>>
