【摘要】 在现行分析水中硝基苯类污染物标准分析方法的基础上,将参加显色反应的水样体积和比色皿厚度各增加一倍,方法检出限由0.20 mg/L降低至0.05 mg/L。用改进法分析很低浓度的硝基苯类水样,具有很好的现实意义。更多还原

【Abstract】 The detection limit of analysis of nitrobenzenes contaminants in water reduced from 0. 20 mg /L to 0. 05 mg /L when doubled the water volume and cuvette thickness based on the standard analytical methods. It has reality effect on using the improved method to analyze low concentrations of nitrobenzene in water samples.更多还原
