摘要
从实验上科学的分析了水质样品预处理的必要性,并从理论和实践上介绍了NH_3-N,总氰、苯胺—硝基苯和六价铬几种监测要素的预处理方法。得出结论:只有进行正确的预处理方法,才能得到具有代表性、可比性、完整性、精确性、准确性的结果。
By experiments, the importance and necessity of pretreatment of water sample has been analzed scientifically,and pretreatment methods for monitred elements including NH3^-N PCN, CI^6+ and Anliine-Nitrobenzcne are introduced.The conclusion is that a result with comparability, integrity, precision and accuracy may be obtained only by corrcct pretreatment method.
