摘要
天然有机物(NOM)是一类分布广泛、成分复杂的有机混合物,可严重影响饮用水的处理效率,并可能对出水水质产生严重的不利影响。因此,为了改进和优化饮用水的处理过程,在研究和实际应用阶段对NOM进行表征和定量以了解其结构特性和反应性具有重要意义。文中先对NOM的富集方法进行了介绍,接着梳理了不同分离方法的依据及作用,最后总结了各类表征方法的原理及应用,以期有助于对NOM和饮用水处理的深入研究。
Natural organic matter(NOM),a complex mixture of organic compounds,has been found in all water bodies.It can not only decrease the efficiency of water treatment processes,but also have a negative effect on drinking water quality.Thus,the analysis and characterization of NOM in order to get information of its structure and reactivity are significant.In this paper,the NOM analysis and characterization methods are summarized,including its concentration methods,fractionation methods,some general parameters and the methods for structural and elemental analysis.
