化工、制药等废水中常含有硝基苯,它侵入机体可引起中枢神经、血液、心脏中毒,并可引起溶血等病症,因此,必须引起人们的重视,加强控制排放量。 硝基苯是难降解的有机物,采用微生物法处理很缓慢,工业上检测硝基苯常采用化学法,(即还原—偶氮—比色)。此法用于较清洁、单一而且硝基苯含量较低的水质。对于复杂化工废水,干扰较大,其回收率和重现性等都不够理想,特别是硝基苯浓度高时,需多次测试。医院临床检测硝基苯常用极谱法,极谱用于水质检测及环境保护等方面也有报导,但多采用滴汞为阴
Chemical industry, pharmaceuticals and other wastewater often contain nitrobenzene, which invades the body can cause central nervous system, blood, heart poisoning, and can cause hemolysis and other diseases, therefore, we must pay attention to strengthen control of emissions. Nitrobenzene is a refractory organic matter, the use of microbial treatment is very slow, often used in industrial nitrobenzene detection chemistry (ie reduction - azo - colorimetric). This method is used for cleaner, single and low nitrobenzene water quality. For complex chemical wastewater, large interference, the recovery and reproducibility, etc. are not ideal, especially nitrobenzene concentration is high, the need for multiple tests. Clinical clinical testing of nitrobenzene commonly used polarography, polarography for the detection of water quality and environmental protection have also been reported, but more with mercury drop
