众所周知，水处理过程中遇到的具体问题与存在的大分子类型有关。本文描述的热解GC-MS分析技术表明，现有模型在准确反映由天然水有机基质组成的复杂混合物方面存在不足。事实上，这些模型中大多数描述的高度浓缩的芳香族核都是由本文报道的研究确定的次要成分。包括27个参考文献、表格和图表。

Specific problems encountered during water treatment are known to be a function of the type of macromolecules present. The pyrolysis-GC-MS analytical technique described in this article shows the inadequacy of existing models to accurately reflect the complex mixture that comprises the organic matrix of natural waters. In fact, the highly condensed aromatic cores described by most of these models were determined by the research reported here to be minor constituents. Includes 27 references, tables, figures.
