这里描述的方法由方法5910联合工作组编制。它将包含在第十九版标准方法中，但现在正在出版，以便与信息收集规则一起使用。该方法旨在指示紫外线吸收有机物的总浓度，这可能与消毒副产品的percursors有关。包括实验方法、结果和讨论、质量控制的细节，以及方法原理和干扰的描述。 显示了实验室间精度数据。包括22个参考文献和表格。

The method described here was prepared by the Joint Task Group for Method 5910. It will be included in the nineteenth edition of Standard Methods but is being published now so that it will be available for use with the Information Collection Rule. The method is intended to indicate the aggregate concentration of UV-absorbing organics, which may possibly be correlated with percursors of disinfection byproducts. Details of the experimental method, results and discussion, and quality control are included, as well as a description of the prinicple of the method and interferences. Interlaboratory precision data are shown. Includes 22 references, tables.
