          摘要:環境監測預處理的目的是為了以達到掩蔽、去除干擾物,保護儀器設備的目的,使后面的化學分析更加精確。針對不同的水樣往往需要對水和廢水監測分析方法(第四版)和各種標準分析方法中的預處理方法進行適當的變更,并列出了一些監測項目的預處理改進方法。本文介紹了預處理的重要性以及集中廢水預處理的方法和應用。

          Environmental monitoring pretreatment technology SongJing Shaanxi University of Science and Technology Xi'an Shaanxi 710021 Abstract: Environmental monitoring is intended to pre-order to achieve the masking to remove interferences, the purpose of protection equipment, so that more accurate chemical analysis of the back. For different water samples often need to ;water and wastewater monitoring and analysis methods (fourth edition) and a variety of standard analytical methods in the preprocessing method of the appropriate changes, and lists some of the pre-treatment improved methods to monitor projects. This article describes the importance of pre-concentrated wastewater pretreatment methods and applications. Keyword: Environmental Monitoring; Wastewater treatment Pretreatment technology
          一、水質預處理的重要性
          由于水質環境是一個綜合和復雜的體系,樣品千差萬別,往往組份錯綜復雜, 一般情況下,一個樣品包括幾十甚至幾百種組份,各組份的濃度有高有低,而且相差很大,從g/L 到 mg/L 甚至于?g/L ,一種物質組份往往以多價形態存在,有單元素及化合態,有無機態和化合態。如鉻有六價鉻、三價鉻、氮有無機氮和化合氮,有機態中又有各種形態的異構體。例如:苯胺有硝基苯胺,對硝基苯胺,
